Fieldpiece SIG1 Gun-Style Infrared Thermometer — HVAC/R | -30°C to 500°C
The Fieldpiece SIG1 is a gun-style infrared thermometer designed for HVAC/R technicians who need fast, non-contact surface temperature measurement for heating and AC diagnosis, electrical hotspot detection, and general field service. The 8:1 field of view, red laser pointer, and bright backlit LCD make it easy to take quick, accurate readings in a range of lighting conditions. A protective PVC cover protects the IR lens, and the recessed display reduces scratching during field use.
Confirm all specifications — including measurement range, accuracy, and emissivity settings — against the Fieldpiece SIG1 manufacturer’s current datasheet before ordering.
