This Infrared Thermometer is useful for measuring temperature in applications where conventional sensors cannot be employed. Offers Ideal for dealing with moving objects ( i.e., rollers, moving machinery, or a conveyor belt), or where non-contact measurements are required because of contamination or hazardous reasons (such as high voltage), where distances are too great, or where the temperatures to be measured are too high for thermocouples or other contact sensors. This infrared thermometer is so easy to use as well...just point and shoot!
