Trotec BP21 Infrared Laser Thermometer

The Trotec BP21 is a handheld infrared laser thermometer with a measuring range of -35 deg C to +800 deg C.

Often refered to as laser pyrometers, these units are used to determine the temperature of a solid non reflective surface. Simply click the trigger button, and measure the temperature.

Compared to other low cost models which often have a poor spot resolution of 6:1 or 8:1, the BP21 has a good optical resolution specification of 12:1. This means at 12 meters distance from the target, the spot measurement size is approx. 1 meter in diameter.

The BP21 also features adjustable emissivity correction and a dual laser pointer, which identifies the approx. spot measuring size. For low light conditions, the BP21 features backlit display.

The BP21 is suitable for measuring targets that are medium to large in size. If you are measuring smaller targets, for example, electrical cables and wires, or extreme temperatures, see the higher specification models from Trotec and Fluke.

Ideal for the measurement of food, pizza ovens, general engineering, hvac, heat loss assessments etc.
