High-Temperature Infrared Thermometer

The CEM DT-8859 is a non-contact infrared thermometer built for electricians and industrial technicians who need to measure extremely hot surfaces from a safe distance. It covers a temperature range up to 1600°C and uses a 50:1 distance-to-spot ratio to target small areas accurately. Adjustable emissivity and laser targeting help adapt the tool to different materials and working conditions.

Upgrade from Lower-Ratio Models

Moving from a 30:1 optical resolution device to this 50:1 unit lets you measure smaller spots at the same distance or stand further back from hazardous heat sources. The jump is worth it when targets are physically small, access is restricted, or safety protocols demand greater stand-off distance. The extended 1600°C ceiling also replaces instruments capped at 1000°C or 1300°C for high-temperature processes.

Sustained Measurement Behaviour

Automatic data hold freezes the reading after the trigger is released so values can be recorded without haste. Max, min, difference and average functions track temperature trends during prolonged scans rather than showing only a momentary snapshot. High and low alarms alert the operator when limits are exceeded, while trigger lock supports continuous monitoring during long inspections.

Questions about this item

What size opening does the 220 mm by 120 mm by 56 mm DT-8859 need in a tool case?

The thermometer measures 220 mm high, 120 mm wide and 56 mm deep, so a case compartment at least that large will accommodate it.

Which step do users often miss when fitting batteries into the DT-8859?

The unit ships without batteries; you must open the rear cover, insert the correct cells observing polarity, then close the cover before first use.

When should the laser targeting on the DT-8859 be checked or realigned?

Verify the laser spot matches the measured area if the thermometer is dropped or after extended high-temperature use up to 1600 °C.
