    Product overview: 53 II Temperature Logging Digital Thermometer

    The Fluke 53 II single-input digital thermometer delivers fast response with laboratory accuracy (0.05% + 0.3°C). And it logs up to 500 points of temperature data to internal memory. You can use the 53 II to measure contact temperature on motors, insulation, breakers, pipes, corroded connections, liquids, and wires with industrial standard J, K, T, E, N, R, or S-type thermocouple temperature sensors. The user-friendly front panel and large, backlit display make it easy to view results and recall logged data for further review. 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 a real-time clock that captures the exact event time
    • Features an infrared USB communication port to allow data to be exported to optional FlukeView Forms® Temperature PC software for further analysis and graphing
    • 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
    • Offers optional ToolPak accessory to hang the thermometer from any metal object (with the rare earth magnet) or secure around a pipe (with hook-and-loop straps) for hands-free operation
