5618B Small Diameter Industrial RTD
Model#:5618B Small Diameter Industrial RTD
Key features
- Secondary level performance with full ITS-90 calibration.
- Sheath diameter of 3.2mm (0.125 in), ensuring reduced response time without compromising precision.
- NVLAP-accredited calibration from -200°C to 500°C, lab code 200706-0.
- Reduced measurement error in short immersion depth applications by conducting less heat between ambient and the sensor.
Product overview: 5618B Small Diameter Industrial RTD
With each probe you will receive a full NVLAP-accredited calibration report. On the report you’ll get the test data and the ITS-90 calibration coefficients that you can easily input into your Fluke Calibration thermometer.
The 5618B is also a great probe to use for calibrating your Fluke Calibration 9132 or 9133 infrared calibrators. In fact, these IR black body heat sources were designed to be calibrated with this type of probe. Now you can calibrate these targets in your own lab!
For use from –200 °C to 500 °C (the six-inch model goes to 300 °C), you won’t find a better industrial standard in this configuration than our 5618B. We recommend using the 5618B PRTs with the 1523, 1524, 1502A, 1529, or 1560 thermometer readouts.
