The Fluke 52 II dual-input digital thermometer delivers fast response with laboratory accuracy (0.05% + 0.3°C). You can use the 52 II to measure two contact temperature inputs simultaneously 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 from both inputs in multiple ways. 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-
Features an electronic offset function that compensates for thermocouple errors to maximize overall accuracy
Measures J, K, T, and E-type thermocouples
Handles temperatures up to 900°C (1600°F)
Presents results in °C, °F, or Kelvin (K)
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
