Product overview: Fluke 51 II Handheld Digital Probe Thermometer

The Fluke 51 II single input digital thermometer delivers fast response with laboratory accuracy (0.05% + 0.3°C). You can use the 51 II to measure contact temperature on motors, insulation, breakers, pipes, corroded connections, liquids, and wires with industrial standard J, K, T, or E-type thermocouple temperature sensors. The user friendly-front panel and large, backlit display make it easy to view results. And the sleep mode feature preserves battery life to give you a typical thousand hours of operation.

Other useful features:

  • Easy-to-access battery door that allows replacing the battery without breaking the calibration seal
  • Comes with splash- and dust-resistant case protected by an impact-absorbing holster and a three-year warranty
  • Powered by three, standard AA batteries -30-
  • Includes an electronic offset function that compensates for thermocouple errors to maximize overall accuracy
  • Handles temperatures up to 900°C (1600°F)
  • Provides a user-friendly front panel that is easy to set up and operate
  • Offers sleep mode to increase battery life; 1000-hour battery life typical

Reviews: Fluke 51 II Handheld Digital Probe Thermometer

Rated 5 out of 5 by from Great Reliability! I bought this 2 years ago and its still in perfect condition! I have never had any trouble with this fluke. It continues to perform the way I need it to and never fails a calibration! I would recommend this fluke to anyone in the Vacuum Furnace indsutry!

Rated 5 out of 5 by from Fluke thermometers accurate and reliable We use the Fluke 51-II units for our online temperature checks. I have found the units accurate and reliable. I also use the Fluke Lab calibration service to keep the units in calibration.
