Designed for ultra-low temperatures, the smart Pt100 Probe with a digital SenseAnywhere Bus interface excels in cryogenic monitoring down to –200 °C. Its class A ceramic sensor delivers accurate measurements across a broad range. Calibration is simplified, as only the Pt100 Probe, not the connected AiroSensor 20-20-43, requires it for precise results.

• Accurate temperature monitoring
• Monitor temperatures from –200 to +200°C
• Pt100 Probe can be tested and calibrated as an individual device
• For monitoring cryogenic applications
• 24/7 data for a full audit and always secure access to your data via the Cloud
• Immediate notification by email, SMS or Voice when limits are exceeded
• The Pt100 probe is designed to be connected to the AiroSensor 20-20-43, which is available for purchase separately

This smart probe featuring a digital SenseAnywhere Bus interface has been especially designed to be used in ultra-low temperature environments for monitoring cryogenic applications down to –200 °C. The class A wire wound ceramic Pt100 sensor ensures accurate measurements over a wide temperature range. The Pt100 Probe can be calibrated because the electronics in the connector is the instrument used to determine the measured value. This means that only the Pt100 Probe needs to be calibrated, not the AiroSensor model 20-20-43 to which it is connected for reliable measurements.
