Fluke Calibration 5615-6-P Secondary Reference Standard Temperature Probe for Platinum Resistance Thermometer, INFO-CON for 1523 or 1524, 152mm L X 4.76mm Diameter, -200°C to 300°C Temperature Range

For those needing faster thermal response, or where diameter and immersion depth are problems. These probes are excellent reference probes for comparison calibrations in a Fluke Calibration dry-well. A printout of sensor resistance is provided in 1 °C increments for each probe. The 5615-6 is calibrated to 300 °C. We’ve tested many of the probes on the market. We’ve used them in our manufacturing facility and tested them in the lab, and this is an excellent secondary standards PRT. Other instruments on the market are priced much higher, have lower stability, or are of lower quality.
