TPI 343 Dual Input K-Type Thermocouple Thermometer

The TPI 343 Dual Input K-Type Thermocouple Thermometer with Field Calibration is a versatile and accurate tool designed for precise temperature measurements across a wide range of applications. With a temperature range spanning from -50°C to 1350°C (-58°F to 2,462°F), this thermometer is suitable for diverse industrial and scientific settings. One of its standout features is the Auto Field Calibration, which ensures accuracy within +/- 1°F through a simple process that takes less than 10 seconds in ice water. This feature, coupled with the ±3°F (±1.6°C) accuracy in the -58°F to 32°F (-50°C to 0°C) range, makes it a reliable instrument even in challenging conditions.

The thermometer offers convenient display modes such as Temp1, Temp2, and Temp1-Temp2, allowing users to monitor multiple temperatures simultaneously. Additionally, the Min/Max Record function captures the highest and lowest temperatures recorded, providing valuable data for analysis. Equipped with a protective rubber boot and an easy-to-read LCD display, the TPI 343 ensures durability and user-friendly operation in various environments. Its Auto Resolution feature adjusts display resolution automatically, and the Hold feature freezes readings for easy recording. With its dual K-type thermocouple inputs and rapid update rate of 2.5 times per second, this thermometer offers efficiency and accuracy in temperature measurement tasks. Whether in laboratories, industrial processes, or HVAC applications, the TPI 343 is a reliable tool for professionals who demand precision and reliability.
