Single Input digital
thermometer for lab, QA, process calibration, food safety and HVAC
Measures J, K, T, and E-type
thermocouples
Presents results in °C, °F,
or Kelvin (K) on a large backlit display
Includes a relative time
clock on MIN, MAX, and AVG to provide a time reference for major events
The Fluke 51 II single input
digital thermometer delivers fast response with laboratory accuracy (0.05% +
0.3°C). You can use the 51 II to measure contact temperature 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. 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
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-
Includes an electronic
offset function that compensates for thermocouple errors to maximize overall
accuracy
Handles temperatures up to
900°C (1600°F)
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
