The Fluke Calibration 5622 Fast Response PRT (formerly Hart Scientific) are the perfect solution for special temperature measurement applications requiring fast response or short immersion over a wide temperature range.
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 32 to 212°F (0 to 100°C) are as fast as 0.4 seconds.
Immersion requirements for these probes is also a plus, ranging from just 10mm to 64mm (0.4 to 2.5 inch), depending on the model. Getting into shallow or tight places is not a problem. And because these probes can handle temperatures from -328 to 662°F (-200 to 350°C), they're more versatile than most thermistors.
5622 PRTs come with two calibration options. Uncalibrated, each of these probes conforms to DIN/IEC Class A requirements with accuracy of ±0.15°C at 0°C and ±0.55°C at 200°C and –200°C. Alternatively, any Model 5622 PRT may be purchased with a Model 1923-4-N ITS-90 Comparison Calibration, which includes seven points from -322.6 to 572°F(-197 to 300°C). With calibration, short-term accuracies are achieved as good as ±0.04 at 0°C.
Readout options for the Model 5622 PRTs include Fluke Calibration's 1523/1524 Handheld Thermometers or the 1529 Benchtop Thermometer. Each of these readouts will read your PRT as a standard DIN/IEC probe or as an individually calibrated PRT.
