Is the PT450S right for your work?

The PT450S combines 480 × 360 native infrared resolution, ≤15mK thermal sensitivity and 50Hz imaging with the advanced controls and inspection workflow of Guide’s PT II platform. It is best suited to professional teams inspecting accessible electrical, mechanical, HVAC and building assets at close-to-moderate working distances.

Its interchangeable lens system allows the same camera body to be configured for large nearby areas, smaller or more distant targets, close-up components and high-temperature equipment. TwinView configurations can also provide two selectable fields of view without changing lenses during the inspection.

Well suited to:

Electrical panels, switchgear and distribution equipment
Motors, bearings, pumps and production machinery
HVAC systems, plant rooms and building diagnostics
Preventive-maintenance and condition-monitoring surveys
Professional thermographers working across varied applications
Teams that need wide-angle, telephoto, macro or high-temperature capability from one camera platform

Consider the PT650S if:

Small or distant targets form a regular part of your work
Inspection images frequently require substantial cropping or enlargement
You want approximately 90% more native detector pixels while retaining the same PT II workflow and lens flexibility

Consider the PT870S if:

Native megapixel thermal resolution is required
Your work involves critical, long-distance, utility or scientific inspections
Maximum image detail and cropping flexibility justify the additional investment

Choose the right lens configuration

Lens choice determines how much of the scene is visible and how many detector pixels are placed on the target at a given distance. Wider lenses show more of nearby scenes, while narrower lenses provide more spatial detail on smaller or more distant targets. No single configuration is best for every application.

Need multiple lenses or a replacement accessory? Contact us before ordering so compatibility and any calibration requirements can be confirmed.

Fixed field-of-view lenses

Choose between wider scene coverage and greater spatial detail on smaller or more distant targets. The figures below are specific to the PT450S.

Wide-angle 45°

Best for: Building surveyors, HVAC engineers and industrial or electrical inspectors covering large nearby targets, plant rooms, switchboards and confined spaces.

Benefit: Provides the widest PT450S view and shortest working distance, allowing more of a nearby scene to be captured in each image.

Consideration: It places fewer detector pixels on small or distant targets than the 25°, 15° or 7° options.

Field of view: 45° × 36°

Minimum focus: 0.15m

D:S ratio: 610:1

Temperature range: −40°C to 650°C

Standard 25°

Best for: Professional thermographers, electrical contractors and industrial maintenance teams carrying out varied inspections at close to moderate distances.

Benefit: The most balanced one-lens PT450S configuration for scene coverage, working distance and target detail.

Consideration: Choose a specialist lens if most work involves confined spaces, very small targets, long distances or temperatures above 650°C.

Field of view: 25° × 20°

Minimum focus: 0.3m

D:S ratio: 1099:1

Temperature range: −40°C to 650°C

Medium telephoto 15°

Best for: Utility, substation, solar and industrial inspectors assessing smaller connections, components or mechanical assets from a moderate stand-off distance.

Benefit: Places more of the PT450S detector on the target than the 25° or 45° options without the very narrow framing of the 7° lens.

Consideration: The narrower view is less efficient for broad surveys and requires at least 0.5m focusing distance.

Field of view: 15° × 12°

Minimum focus: 0.5m

D:S ratio: 1818:1

Temperature range: −40°C to 650°C

Telephoto 7°

Best for: Utility, power-network, solar and industrial specialists inspecting overhead lines, substation components or other small and inaccessible targets from longer distances.

Benefit: Delivers the greatest spatial detail and distance-to-spot ratio available on the PT450S for demanding long-distance inspections.

Consideration: The very narrow view and 5m minimum focusing distance make it unsuitable for overview or nearby inspection work.

Field of view: 7° × 5°

Minimum focus: 5m

D:S ratio: 4000:1

Temperature range: −40°C to 650°C

Macro configuration

Designed specifically for very small components at a controlled close working distance.

High-temperature configuration

A dedicated 25° lens extends the PT450S into a 400°C to 2,500°C specialist range and is only necessary when targets may exceed 650°C.

Macro

Best for: Electronics engineers, R&D teams and quality-control specialists inspecting circuit boards, assemblies and other very small components.

Benefit: Provides 3× magnification and 48.1µm spatial resolution across a 23.1 × 18.5mm viewed area.

Consideration: It requires a fixed 100mm working distance and is intended for controlled close-up work rather than general handheld inspections.

Viewed area: 23.1 × 18.5mm

Working distance: 100mm

Spatial resolution: 48.1µm

Magnification: 3×

Up to 2,500°C

High-temperature 25°

Best for: Process, metallurgy and maintenance engineers inspecting furnaces, kilns, foundries, refractory linings and other extreme-temperature assets.

Benefit: Combines the balanced 25° view with a dedicated 400°C to 2,500°C measurement range.

Consideration: It is a specialist configuration and is only necessary when targets may exceed the standard configurations' 650°C limit.

Field of view: 25° × 20°

High-temperature range: 400°C to 2,500°C

TwinView dual field-of-view configurations

TwinView DFOV configurations provide two selectable optical fields of view in one lens, allowing the view to change without removing the lens. They do not provide continuous optical zoom.

Guide PT450S standard and wide-angle TwinView dual field-of-view lens

DFOV standard 25° + wide-angle 45°

Best for: Professional thermographers, building surveyors, HVAC engineers and industrial or electrical teams moving between general inspections, confined spaces and large nearby assets.

Benefit: Switches between the balanced 25° view and wide 45° view without changing lenses.

Consideration: Neither view increases detail on distant targets; choose the 15° DFOV or dedicated 7° lens when reach is more important.

Fields of view: 25° × 20° / 45° × 36°

Minimum focus: 0.3m / 0.15m

D:S ratio: 1099:1 / 610:1

Temperature range: −40°C to 650°C

Guide PT450S standard and medium telephoto TwinView dual field-of-view lens

DFOV standard 25° + medium telephoto 15°

Best for: Utility, substation, electrical and industrial maintenance professionals who need both an overview and more detail on smaller or moderately distant targets.

Benefit: Switches between an all-purpose 25° view and a more detailed 15° view without changing lenses, making it the most versatile PT450S configuration for mixed-distance inspections.

Consideration: It does not provide the wider coverage of the 45° lens or the long-distance reach of the dedicated 7° configuration.

Fields of view: 25° × 20° / 15° × 12°

Minimum focus: 0.3m / 0.5m

D:S ratio: 1099:1 / 1818:1

Temperature range: −40°C to 650°C

Guide PT II PT450S FAQs

Clear answers to the most common questions about selecting, ordering and using the PT450S.

The PT450S is designed for professionals carrying out electrical, mechanical, industrial and maintenance inspections who need detailed thermal images, accurate temperature measurements and the flexibility of interchangeable lenses. Its 480 × 360 infrared resolution, 15mK thermal sensitivity and 50Hz frame rate make it well suited to inspecting equipment such as electrical systems, motors, pumps, bearings, machinery, HVAC equipment and other industrial assets.

If you regularly need to resolve smaller targets at greater distances, the PT650S provides a higher 640 × 512 infrared resolution. For demanding inspections where maximum image detail and long-range target identification are critical, the PT870S offers 1280 × 1024 resolution.

The best configuration depends on the equipment you inspect and the distances you typically work from. The standard lens is a versatile choice for general industrial and electrical inspections. Wide-angle lenses are useful when you need to capture large equipment or confined spaces, while medium telephoto and telephoto lenses provide greater detail when inspecting smaller or more distant targets.

The PT450S also supports macro, TwinView DFOV and high-temperature lens options, allowing the camera to be configured around your particular inspection requirements.

Yes. The PT450S uses an interchangeable-lens system, so you are not locked into the lens configuration you purchase initially. Additional lenses can be added later as your inspection requirements develop, allowing one camera to cover a wider range of applications.

Contact Corey Technical before purchasing another lens so we can confirm compatibility, calibration requirements and availability.

The PT450S measures from -40°C to 150°C and 0°C to 650°C, with automatic switching between measurement ranges. An optional high-temperature lens extends measurement capability to 2500°C for suitable high-temperature applications.

These specialist configurations are only necessary when target temperatures may exceed 650°C.

The PT450S has a 480 × 360 infrared detector and can produce super-resolution images up to 960 × 720. Its 15mK thermal sensitivity helps reveal relatively small temperature differences, while the 50Hz frame rate provides a fluid live thermal image when scanning equipment.

The PT450S can help identify abnormal heat patterns associated with electrical and mechanical problems, including overheating connections, unevenly loaded components, motor abnormalities, bearing issues, pump problems and other developing faults.

Thermal imaging does not by itself diagnose the cause of every fault, but it gives you temperature information that can help identify abnormalities quickly and decide where further investigation or maintenance is required.

Yes. The PT450S stores thermal images with temperature information and is compatible with Guide's ThermoTools PC software and FocusIR mobile software for image analysis and reporting. This allows captured inspections to be reviewed and analysed after the site visit.

No. The PT450S operates as a complete standalone thermal camera, allowing images and radiometric video to be captured, reviewed, analysed and stored directly on the device.

Guide ThermoTools for Windows supports more detailed analysis and report preparation, while the FocusIR app supports compatible mobile viewing, transfer and analysis workflows. Both Thermotools and FocusIR are free to use. No ongoing subscription is required to operate the camera.

Yes. All Guide's thermal cameras and lens configurations available at Corey Technical are prepared by Guide Sensmart and supplied with a manufacturer calibration certificate.
