Product Description

The TPI 377 is a versatile dual-mode thermometer combining non-contact infrared measurement with a built-in K-type thermocouple probe input — one of the most flexible temperature instruments in the TPI line. Non-contact IR mode measures -58°F to 1112°F (-50°C to 600°C) at a 12:1 D:S ratio, suitable for aircraft engine diagnostics, brake temperature monitoring, and HVAC heat exchanger surveys from a safe distance. The K-type probe input extends range to 2462°F for contact applications including exhaust manifold temperatures and high-temperature process monitoring. Adjustable emissivity (0.10 to 1.00) compensates for different surface types. Min/Max/Average recording tracks temperature changes during run-up testing and thermal cycling.
