A laboratory-grade testing instrument, Fluke's 54 II thermometer is also the best overall model available in Fluke's 50 series of digital thermometers.

The 54 II measures temperature via the use of various different thermocouples types. Like other models in the range it is compatible with J, K, T and e type thermocouples; this is increased further by the inclusion of R, S and N thermocouple capabilities, bringing up the total number of connectible thermocouples up to 7. The 54 II is also a dual input digital thermometer which means it can be used with a combination of two thermocouples at the same time for comprehensive temperature measurement analysis.

Depending on the type of thermocouple equipped to the unit, the overall temperature measurement capabilities of the device change. Here's the list of possible ranges and thermocouple types:

  • 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 °C
  • R and S Type: 0 °C to 1767 °C

The Fluke 54 II is suitable both for single measurements of alternatively can be used to track temperatures over a time period thanks to the devices' in-built memory which can store up to 500 data points. Users can also choose the overall recording interval, so its possible to connect up the unit, leave it measuring and then view the data at a later point. The 54 II also comes with a USB port that allows it to interface with PC and via the use of Fluke's FlukeView Forms Temperature PC software this data can be interacted with further.
