Fluke Calibration’s 5623B Precision RTD Freezer Probe is the solution when application requirements demand low temperature exposure. From the sensing element to the end of the probe cable, the 5623B is specially sealed, inhibiting the access of moisture when the probe is subjected to temperatures as low as -100°C. The entire construction of the probe is designed for full immersion, such as use in a liquid bath, and to endure temperatures from -100°C to 156°C. The 5623B boasts a 6.35 mm (0.25 in) dia. × 125 mm (6 in) long Inconel™ sheath and an accuracy of ± 0.05 °C over its full range – which includes calibration uncertainty and short-term drift.
Each Fluke Calibration 5623B comes supplied with a full NVLAP-accredited calibration report. The report includes test data along with ITS-90 calibration coefficients which can be entered into Fluke Calibration thermometer readouts, such as the 1523, 1560, 1524, 1502A or 1529 models.
