The 5623B, precision “freezer probe," is specially sealed from the sensing element to the end of the probe cable, preventing ingress of moisture when exposed to temperatures as low as -100°C. The entire assembly withstands temperatures over its full range (-100°C - 156°C), which is ideal for verification of freezers or autoclaves where a thermo-well isn’t available. The 5623B assembly can be fully immersed in fluids when the application may require use in a liquid bath. The 5623B is available in a 6.35 mm (0.25 in) dia. × 125 mm (6 in) long Inconel™ sheath. With accuracy (that includes calibration uncertainty and short-term drift) of +/- 0.05°C over its full range, the 5623B is just right as a secondary standard for calibration of other process sensors.

Most Fluke Calibration readouts make an excellent companion for the 5623B. We recommend the use of the 1523, 1524, 1502A, 1529, or 1560 thermometer readouts.

With each 5623B, you receive a full NVLAP-accredited calibration report. This report includes test data and ITS-90 calibration coefficients to enter into your Fluke Calibration thermometer readout.

• Fully immersible probe assembly to -100°C
• NVLAP-accredited calibration and ITS-90 coefficients included
• Accuracy to +/- 0.05°C over the full range
