Fluke 5622 Thermistor Probe | Precision Temperature

The Fluke Calibration series of fast response PRTs includes four models with stainless steel sheaths ranging from 0.5 to 3.2 mm (0.02 to 0.125 in) in diameter. Because these high-quality wire-wound sensors come in small packages, heat transfer to the sensors occurs quickly. Time constants from 0 °C to 100 °C are as fast as 0.4 seconds.

Immersion requirements for these probes are also a plus, ranging from just 10 mm to 64 mm (0.4 to 2.5 inches), depending on the model. Getting into shallow or tight places is not a problem. And because these probes can handle temperatures from –200 °C to 350 °C, they’re more versatile than most thermistors.

5622 PRTs come with a Model 1923-4-N ITS-90 Comparison Calibration, which includes seven points from –197 °C to 300 °C. Short-term accuracies are achieved as good as ±0.04 °C at 0 °C.

Readout options for the Model 5622 PRTs include Fluke Calibration's 1523 Handheld Thermometers, 1524 Handheld Thermometers, or the 1529 Benchtop Thermometer. 5622's purchased with a 1523/1524 will have the calibration coefficients programmed into the probe's smart connector.

Whatever your thermometry requirements are, come to Fluke Calibration. No one else offers a wider range of standards-quality reference thermometers.
