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.

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

• Detect trapped moisture and damaged insulation (flat roofs shine here).

Quality, R&D, and Process

• Monitor heat profiles and fill levels in closed tanks.
• Board-level hot spot checks; log thermal processes with radiometric video.

High-Temperature & Utilities

• Image furnaces, kilns, and smelters at a safe distance (option to 1200 °C).
• Scan transformers and lines; check PV modules for faults.
