Have a question?
The DONGCHENG HD133702 Infrared Thermometer reads surface temperatures from a distance across a wider range, -50°C to 680°C (-58°F to 1256°F), with a response time under 0.5 seconds. The distance-to-spot ratio is 12:1, so it reads a smaller spot from farther away than the 10:1 model. Adjustable emissivity from 0.1 to 1.0 lets you set the right value for shiny metals, painted surfaces, and plastics for more accurate readings. It switches between °C and °F, powers off automatically, and comes with 2 AAA (R03) batteries. It is made for electricians, HVAC technicians, mechanics, and industrial maintenance teams.
This is not a medical thermometer and is not for use on people.
