Purpose and user
The CEM DT-9862 is a non-contact infrared thermometer with dual laser targeting and a built-in 2.2" colour TFT LCD screen. It captures both still images and video, storing files on an 8G memory card. Electricians and maintenance technicians use it to inspect panels, motors and HVAC components from a safe distance.
Distance-to-spot ratio
A 50:1 optical ratio lets the operator measure small targets at long range without losing accuracy. The visible-light camera records at 640 by 480 pixels, giving 300,000 pixels of visual reference alongside each thermal reading. Adjustable emissivity from 0.1 to 1.0 in 0.01 steps matches different surface finishes.
Sustained operation
Response time stays below 300 milliseconds during continuous scanning, and the instrument maintains ±1% precision across the -50 to 2200°C high-temperature range. A type K thermocouple input adds contact measurement when needed, while air temperature and humidity sensors log ambient conditions for trend analysis.

Questions about this item
How does the 50:1 distance-to-spot ratio affect real-world measurements?
The 50:1 ratio lets you measure a one-centimetre spot from fifty centimetres away, so you can read small targets at a safe distance without climbing ladders or reaching into live panels.
What does the adjustable emissivity range of 0.1 to 1.0 actually limit?
Emissivity steps of 0.01 let you match the surface you are measuring — from shiny metal near 0.1 to painted or oxidised surfaces near 1.0 — so the infrared reading stays accurate across different materials.
What physical slot or mount does the 8G memory card need?
The unit accepts a standard micro-SD card up to 8 GB for storing 640 × 480 photos and video clips; no special adapter or proprietary slot is required.
