Testo 890 Thermal Imager – One-Lens Kit
Overview
The Testo 890 delivers crisp thermal images for tough jobs in industry and buildings. It uses a 640 × 480 detector and boosts to 1280 × 960 with SuperResolution. Sensitivity is < 40 mK, so small temperature changes are easy to see.
Record fully radiometric video for process work. Every pixel is a measurement point for deep analysis on the PC.
Key Features
- High detail: 640 × 480 IR; SuperResolution up to 1280 × 960.
- High sensitivity: NETD < 40 mK @ 30 °C.
- Smart workflow: JPEG save, optional sequence capture, SiteRecognition, panorama assistant.
- Easy handling: camcorder grip, wrist strap, fold-out display, one-hand use.
- High-temp ready: optional range up to 1200 °C.
- Mould risk mode: dewpoint overlay (red / yellow / green). Works best with the optional radio humidity probe.
- Integrated visual camera: with power LEDs for clear documentation photos.
- Auto-focus + close focus: down to 10 cm.
- Voice notes: record comments via included headset.

Applications
Preventive Maintenance
- Find hot spots under load to cut downtime and fire risk.
- Electrical: switchboards, PV arrays, LV/MV/HV gear.
- Mechanical: motors, bearings, shafts, rotating plant.
Building & Energy
- Spot insulation gaps, thermal bridges, and air leaks.
- Check windows and doors for air-tightness.
- Run energy audits and document losses with clear images.
- Use panorama assistant to stitch whole façades.
- Show mould risk areas with the humidity mode.
HVAC & Plumbing
- See temperature balance across coils, ducts, and rooms.
- Trace underfloor loops and compare flow/return temps.
- Pinpoint leaks and pipe breaks with minimal opening.
Roofs & Envelopes
