Michell Instruments has developed a new Pura range of trace moisture transmitters for applications where purity of gases is of critical importance.

The new Pura range is based on Michell’s tried-and-tested ceramic impedeance moisture sensor and is capable of measuring dew pointes between -120 and -40°C dew point, or, in terms of absolute moisture content, 1 ppbV to 126.71ppmV.

This focus towards drier measurements optimises the performance for applications where the near-total absence of moisture is crucial to quality.

The Pura is simple to install and easy to operate. An optional display is also available to create a highly accurate, yet cost-effective hygrometer. Routine maintenance is also simple as the Pura is included in the Michell Instruments’ sensor exchange program. Effectively providing a life-time warranty, the exchange program allows users to ensure their sensor is always calibrated, while keeping their process running.
