Data Logging up to 500 points of data with user adjustable recording interval

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, E, R, S, and N-type thermocouples

Readout in °C, °F, or Kelvin (K)

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 allows the thermometer to hang from any metal object (with the rare earth magnet) or secure around a pipe (with hook-and-loop straps) for hands-free operation

Fluke 54 II B dual input digital thermometer can log up to 500 points of data to internal memory. Fast response and laboratory accuracy (0.05% + 0.3 °C). Take contact temperature for checking motors, insulation, breakers, pipes, corroded connections, liquids, and wires with industrial standard J, K, T, E, N, R, and S type thermocouple (temperature sensors).
