TFA Dostmann RAY LIGHT Infrared Thermometer 12:1 Optics -50 to 400°C Non-Contact IR Measurement (31.1143.13)

The RAY LIGHT stands out with its 12:1 optical resolution, letting you measure smaller targets from a safer distance than typical 8:1 thermometers. Its adjustable emissivity and fast response make it suitable for HVAC, automotive, and industrial checks.

Highlights

• Wide temperature range from -50 to 400°C (-58 to 752°F)
• 12:1 distance-to-spot ratio for precise non-contact measurement
• Adjustable emissivity (0.10–1.00) for different surfaces
• Backlit LCD with data hold and min/max/avg/diff functions
• High/low temperature alarm and single laser pointer

In daily use

Point, pull the trigger, and read the temperature in under half a second. The backlit display remains readable in dark corners, and the auto power-off saves battery life. Powered by two AAA batteries, it is lightweight and comfortable for one-handed operation.
