Fluke 52 Ii Dual Probe Digital Thermometer

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.

• Easy-to-access battery door that allows replacing the battery without breaking the calibration seal

• 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
• Dual-input digital thermometer for lab, QA, process calibration, food safety and HVAC
• Shows any combination of T1, T2, T1-T2, plus MIN, MAX, or AVG on the large backlit dual display
• Features fast response and laboratory accuracy (0.05% + 0.3°C)
• Includes a relative time clock on MIN, MAX, and AVG to provide a time reference for major events
