Fieldpiece SIG1 Gun-Style Infrared Thermometer
The Fieldpiece SIG1 is a gun-style infrared thermometer built for fast, non-contact surface temperature checks across HVAC, air conditioning and electrical maintenance work. With a 10:1 field of view, bright blue backlit LCD and red laser guide, it makes quick and accurate readings easy — even in dark roof spaces, plant rooms and tight service areas.
The SIG1 works faster than thermistor-based instruments and covers a wide range of -30°C to 500°C (-22°F to 932°F). A protective PVC cover protects the IR lens, the recessed display reduces scratching, and Auto-Power Off conserves battery life.
