Fluke 52 II

Fluke 52 II – Overview

The Fluke 52 II is a dual-input thermometer built for precision contact temperature measurement using J, K, T, or E-type thermocouples. It displays both probe readings, their difference, and statistical values (MIN, MAX, AVG) on a large, backlit dual display. Designed for lab, process, HVAC/R, food safety, and QA environments, it offers laboratory-grade accuracy, long battery life, and rugged protection against splash and dust.

Key Features

• Dual thermocouple inputs allowing two simultaneous measurements (T1, T2) plus T1-T2 differential

• Supports J, K, T, and E-type thermocouples

• MIN, MAX, AVG display modes with relative time clock reference

• Dual, large backlit display shows readings clearly under varied lighting

• Fast response and laboratory accuracy of 0.05 % + 0.3 °C (above −100 °C)

• Sleep mode to extend battery life (~1000 hours typical)

• Easy-access battery door that doesn’t break calibration seal

• Electronic offset function to correct for thermocouple errors

• Supplied with two bead-type probe thermocouples

• Rugged housing with splash and dust resistant case; impact-absorbing holster; three-year warranty
