CEM Professional Infra Red Thermometer with dual laser is a very handy device to be used for all trouble-shooting engineers for taking temperature of areas that are inaccessible, moving targets and for surveillance of heat at various points in an area. These have adjustable emissivity between 0.10 to 1.00 to cover various materials whose temperature is measured.

These have Distance to sighting ratio of 12:1 and 20:1. This means that from a distance of 12 inches the area whose temperature is being measured would have a diameter of 1 inch. Similarly for 20:1 from a distance of 20 inches the area whose temperature is being measured would have a diameter of 1 inch. Hence the longer you want to keep the distance from the target the higher the Distance to sighting ratio should be

The instrument has a Red Dual Laser marker through which the user can pin point the exact area of the target whose temperature is to be measured. The temperature being measured is for the area between the two laser points.

In these meters you can set the lower and higher temperature. As soon as the temperature being measured exceeds the set limit the color of the backlit LCD changes.
