53 II Temperature Logging Digital Thermometer

Key features

Single Input digital thermometer with data logging for lab, QA, process calibration, food safety and HVAC
Logs up to 500 points of data at user adjustable recording intervals
Measures J, K, T, E, R, S, and N-type thermocouples
Presents results in °C, °F, or Kelvin (K) on a large backlit display
Provides a recall function to easily review logged data

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.
