Choose the Testo 883-1 for component-level detail
The Testo 883-1’s narrower 30° × 23° lens places more detector pixels across a target than the 883-2’s wide-angle lens when both cameras are used from the same position. This makes it the stronger choice when the inspection depends on distinguishing smaller components rather than fitting a large area into one image.
Choose the Testo 883-1 for:
- Electrical panels, switchgear, breakers and cable terminations
- Motors, bearings, pumps, drives and production machinery
- Preventive-maintenance routes across industrial facilities
- Defined targets inspected at ordinary cabinet and plant-room distances
- Repeat inspections that require organised, traceable reporting
Choose the Testo 883-2 for wider coverage
The Testo 883-2’s 42° × 32° lens captures substantially more of the scene from the same working position. It is designed for situations where the target is physically large or there is not enough room to step farther back.
Choose the Testo 883-2 for:
- Building-envelope surveys and energy assessments
- Walls, windows, roofs, floors and complete room sections
- Insulation defects, thermal bridges and heat-loss investigations
- Underfloor heating, concealed pipework and moisture investigations
- HVAC equipment and plant-room installations viewed at close range
What does the field-of-view difference mean in practice?
From approximately two metres away:
- The 883-1’s 30° lens captures an area approximately 1.07 metres wide
- The 883-2’s 42° lens captures an area approximately 1.54 metres wide
The 883-2 therefore fits more of a wall, room or installation into each thermal image. The 883-1 sacrifices that extra width to place more pixels across individual electrical or mechanical components.
These figures are approximate and describe horizontal scene width.
When should you choose the dual-lens configuration?
Both models are available with an additional 12° × 9° telephoto lens. Choose the dual-lens configuration when your work includes small or distant targets that cannot be approached closely, including outdoor switchgear, substation components, elevated connections and equipment behind established barriers.
The telephoto lens has a 0.7 mrad spatial resolution, placing substantially more pixels across a distant target than either supplied lens.
The dual-lens configuration also adds:
- 12° × 9° telephoto lens
- Additional rechargeable battery
- Desktop dual-battery charging station
Choose:
- 883-1 dual lens for detailed electrical and industrial inspections across close-to-longer working distances
- 883-2 dual lens when you need both wide building coverage and occasional long-distance inspection capability
