Description 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 Specifications Temperature accuracy Above -100°C J, K, T, E, and N-type: ±[0.05% 0.3°C]1 R and S-type: ±[0.05% 0.4°C]1 Below -100°C J, K, E, and N-types: ±[0.20% 0.3°C]1 T-type: ±[0.50% 0.3°C] Temperature J-type -210°C to 1200°C K-type -200°C to 1372°C T-type -250°C to 400°C E-type -150°C to 1000°C N-type -200°C to 1300°C1 R and S-type 0°C to 1767°C1 Temperature scale ITS-90 Applicable standards NIST-175 Display resolution 0.1°C, 0.1 K < 1000 1°C, 1 K ≥ 1000 1.
