Dwyer Series IR400 & IR500 Infrared Temperature Thermometers

12:1 Distance-to-Target Size Ratio, Laser Sighting

Take fast, easy and safe temperature measurements with the Model IR400 and IR500 Infrared Temperature Thermometers. Choose between the IR400 with its single point laser sighting or the IR500 with an 8-point circular laser sighting. The emissivity is fixed at 0.95 to accurately measure concrete, asphalt, rubber and oxidized metals. The temperature is displayed on the 4-digit LCD display in °F or °C. Additional features include MAX temperature display, 7 second display hold, LCD backlight and hard carrying case.
