The 20948 cryogenic freezer probe has secondary standard level precision. It's flexible, holds its shape and stays on place.

• Low uncertainty: ±0.010ºC at TPW
• Calibration: NIST traceable, NVLAP Accredited (Lab Code 200706-0) calibration report
• Compatibility: 100 ohm resistance at 0ºC make the 20948 compatible with most readout devices
• Stability: Proprietary seal locks out moisture and contaminants to insure stability
• Durability: Not for use in vibration service, more durable than an SPRT
