The Fluke Model 53 Thermometer is a microprocessor-based, digital thermometer designed to use external J-, K-, T-, E-, R-, S-, and N-type thermocouples (temperature probes) as temperature sensors.

The Fluke 53 II features Min / max / avg with relative time clock and an electronic offset function allowing compensation of thermocouple errors to maximise overall accuracy.


Relative time clock on MIN, MAX, and AVG provides a time reference for major events.
Electronic Offset function allows compensation of thermocouple errors to maximize overall accuracy.
Measures J, K, T, and E-types of thermocouples.
Additional thermocouple types R, S, and N (for a total of 7 different types).
Recall function allows logged data to be easily reviewed on the meter display.
Infrared USB communication port allows data to be exported to optional FlukeView Forms.
Data Logging up to 500 points of data with user adjustable recording interval.
Readout in ºC, ºF, or Kelvin (K).
Large backlit dual display.
Splash and dust resistant case protected by impact absorbing holster.
User-friendly front panel is easy to set up and operate.
Sleep mode increases battery life; typical 1000-hour battery life.
Battery door allows easy battery replacement without breaking the calibration seal.
Optional ToolPak accessory.
