CEM DT-8858 50:1 1300°C Infrared Thermometer

High-temperature infrared thermometer

The CEM DT-8858 measures surface temperatures up to 1300°C with a 50:1 distance-to-target ratio. It suits electricians, HVAC technicians and maintenance engineers who need non-contact readings on live equipment or hard-to-reach components. The 150 ms sampling time and 1 % accuracy support quick inspections on production lines or electrical panels. Adjustable emissivity allows reliable results across different material surfaces.

Simple setup with battery and manual constraints

The unit ships without batteries because air-freight rules prohibit them; users must source standard cells locally. No English manual is included in the box, so operators should request documentation from support after purchase. Laser targeting and a white backlit LCD make aiming and reading straightforward in dim environments. Trigger lock enables continuous monitoring without holding the button down.

Consistent performance during extended measurement

Automatic data hold captures the last reading when the trigger is released, while max, min, difference and average functions track trends over time. High and low alarms alert operators when temperatures exceed preset limits during prolonged runs. The 50:1 optical resolution maintains accuracy on small targets even at distance, preventing drift caused by measuring larger surrounding areas. Auto power-off preserves battery life between successive checks.
