SF6 Measurement Solutions

Long-Term Reliability with No Humidity, Purity, or Pressure Shelf-Life Concerns

The 973-SF6 ensures consistent and accurate measurements over extended periods, even when stored for 2-3 years, thanks to its reliance on fundamental physics for humidity and purity measurements, eliminating the need for sensor-based modules with limited shelf lives.

Why RH SF6 Measurement?

The 973-SF6 offers long-term riliability with no humidity or purity shelf-life concerns, using fundamental physics for accuracy, stable storage up to 3 years, and quick SO2 module replacement.

SF6 Measurement
Product Features

Zero Humidity or Purity Shelf-Life

Humidity and purity measurements rely on fundamental physics (condensation principles) rather than sensors or modules, ensuring long-term accuracy.

Stable Temperature Sensors

The only components with shelf-life considerations are the temperature and pressure sensors, which are highly stable and unaffected by storage.

Easy SO2 Module Replacement

The SO2 module, with a shelf life of 18-24 months, can be quickly replaced in 30 seconds using 4 small hex screws, ensuring minimal downtime.

Extended Storage Capability

The system can be stored for up to 2-3 years without affecting humidity and purity readings, making it ideal for infrequent use or backup applications.

Physics-Based Measurements

Humidity is measured via dew point condensation, and purity is determined through SF6 condensation, ensuring reliable and repeatable results.

Convenient Design

The SO2 module housing is easily accessible on the back panel, allowing for quick and hassle-free replacements.
