Testo 810 Infrared Thermometer for Air and Surface Temperature

The Testo 810 Infrared Thermometer is a versatile and portable instrument designed for professional and DIY use, combining the ability to measure air temperature and perform non-contact surface temperature readings with a single, compact device. This dual-functionality makes it an essential tool for a wide range of diagnostic and quality control tasks.

It features advanced infrared technology with a 1-point laser for precise spot marking and 6:1 optics, allowing you to target specific areas from a safe distance. The clear display shows the current temperature, differential readings (for example, between a window surface and the ambient air), and minimum/maximum values recorded. A handy hold function freezes the reading on the screen, while adjustable backlight illumination ensures visibility in low-light conditions.

For accurate surface readings, the device's emissivity is fully adjustable, allowing you to calibrate for different materials. This feature, combined with the ability to display the difference between air and surface temperature, provides deep insights into thermal performance and potential issues like heat loss or insulation faults.

Key Applications

• HVAC & Building Inspection: Quickly identify drafts, insulation deficiencies, and thermal bridges.
• Electrical Maintenance: Safely check for overheating components in switchgear, fuse boxes, and motors.
• Automotive Diagnostics: Measure engine bay temperatures, exhaust systems, and cabin climate control output.
• Food Safety & Catering: Monitor storage temperatures, check cooking surfaces, and ensure compliance with food hygiene standards.
• Home Energy Audits: Locate areas of heat loss around windows, doors, and walls to improve efficiency.

Supplied complete with a protective cap, batteries, a calibration protocol, and a convenient carry pouch for transport and storage, the Testo 810 is a user
