The most advanced quartz technology dew point sensor available. Newly developed moisture sensitive materials provide superior signal sensitivity under ultra-low humidity conditions, providing long term, stability to measure pressure dew points down to -110°C (-166°F).
The innovative temperature compensation algorithm and multi-point temperature compensation calibration greatly improves the sensor’s temperature drift and ensures high-precision measurements over a wide temperature range. The precision sensor design compensates for contamination and aging, providing long-term, reliable, high-accuracy measurements.
The sensor is available with an in-built display or without a display. The display option includes an alarm relay and allows you to adjust the dew point settings (gas type, measurement units, modbus and 4-20mA settings, etc).

Important
- This sensor is NOT recommended for refrigerant dryers.
- This sensor is NOT recommended for dew points above -20°C (-4°F)
- A minimum flow rate of > 1L/min is required for the sensor to read accurately
- The sensor must be installed in an upright position, after the dryer.
- Incorrect wiring or installation can damage the sensor and void the warranty. If you aren’t sure how to install or wire the sensor, please contact us. Full installation and wiring instructions are available in the User Manual.
