Mestek Infrared Thermometer IR03B NonContact Gun -50 to 600C

The Mestek IR03B Infrared Thermometer is a rugged, handheld non-contact gun designed for fast, safe surface temperature measurements in industrial environments. Covering -50°C to 600°C with a 12:1 object distance ratio, this smart infrared thermometer delivers quick readings on a bright digital display. The adjustable emissivity (0.1–100) lets you tailor accuracy for a variety of materials—from painted metals to plastics and glass. Powered by two AAA batteries (not included) and featuring automatic shutdown after 30 seconds, the IR03B is built for reliability on the shop floor, in HVAC, manufacturing, and food service settings. Important: Not suitable for measuring body surface temperature, forehead, or babies.
