The Fluke 51 II is a single-input digital thermometer that is compatible with J, K, T and E type thermocouple probes.
With ultra-fast response and laboratory accuracy of 0.05% + 0.3°C, Fluke's 51 II is a must for professional temperature measurements in practically any application.
Fluke 50 Series II Digital Contact Thermometers
The overall measurement range of the Fluke 51 II varies depending on the probe type used. Measurements can be output in Kelvin, Celsius or Fahrenheit and the following measurement ranges are possible for each different type of thermocouple:
- J Type: -210°C to 1200°C (-346°F to 2192°F)
- K Type: -200°C to 1372°C (-328°F to 2501°F)
- T Type: -250°C to 400°C (-418°F to 752°F)
- E Type: -150°C to 1000°C (-238°F to 1832°F)
The Fluke 51 II digital thermometer can be used in any environment thanks to its backlit LCD screen and splash/dust resistant casing (ideal for use in industrial conditions).
As well as individual measurements the 51 II can also calculate and display the MAX, MIN and AVG values taken over a period of time. A relative time clock facility built into the thermometer also provides a time reference for major events, making it easier to determine problems.
Fluke 51 II Thermometer Key Features
- Single input digital thermometer suitable for use with type J, K, T and E thermocouple probes
