Maintenance professionals monitor motor malfunctions, research heating and ventilation problems, and monitor electrical motor performance safely and easily with the professional Raytek STPro thermometer. Handheld, and portable, the Raytek STPro infrared thermometer stand up to the day-to-day usage professionals require of their equipment.
The STPro leaps ahead of standard entry level models by providing expanded temperature ranges, higher resolution optics, tighter accuracy and brighter laser sighting. The single dot Extra Bright Laser Point sighting system makes the center point of the measurement area more visible in all conditions, especially outdoors. In less than a second, the large temperature display provides current and MAX surface temperatures.
For equipment maintenance, and heating and ventilation troubleshooting, the professional STPro thermometer makes troubleshooting quick and easy.
Use the ST20 XB within six feet of the intended target. At greater distances, the measured area will be larger (approximately the distance divided by twelve).

Service from Arizona Tools was great ! I'm a first time buyer. I'll use them again. The Raytex ST20XB Temp. gun works as advertised. No issues, I'm going to purchase another.
