Field probes are designed for the industrial process environment and quickly reach temperature. They weigh less than 8.2 kg and take up little space, making them easy to transport. Field environmental conditions are often unstable with large temperature swings.

Each field probe has built-in temperature gradient compensation (patent pending) that adjusts control characteristics to ensure stable performance in unstable environments. In fact, all specifications are guaranteed in the ambient range of 13 °C to 33 °C.

frequently asked questions

do fluke meters need to be calibrated?

As with any type of tool or piece of equipment, at some point, it will be necessary to calibrate a Fluke multimeter. Whether you use it as a hobby or in a highly regulated industry, to get consistent and accurate readings from the Fluke you need to calibrate it regularly

Is Fluke Calibration free?
