The FLUKE-52-2-CAL Fluke dual-input digital thermometer delivers fast response with laboratory accuracy (0.05% + 0.3°C). Temperature range from -418 to 2501°F (-250 to 1372°C). You can use the FLUKE-52-2-CAL 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.
