Contact Temperature Testers

TPI contact temperature testers are accurate, reliable, and built to last. Models 341K, 343 and 367D can be auto field calibrated to system accuracy (tester plus probe) of +/- 1°F in less than 10 seconds in ice water.

AUTO FIELD CALIBRATION Perform ice bath calibration to achieve ±1°F system accuracy within the 30°F to 120°F temperature range. Calibration is an easy two-step process performed with instrument keypad, no additional tools needed.
