Trace moisture transmitters for measuring contamination
Michell’s Pura trace moisture transmitters were developed for applications where purity of gases is of critical importance and even trace amounts of moisture are considered to be a contaminant. The Pura is capable of measuring dew points between -120 and -40°C dew point, or, in terms of absolute moisture content, 1 ppbV to 126.71ppmV. This focus towards drier measurements optimizes the performance for applications such as semiconductor manufacture, where the near-total absence of moisture is crucial to quality. An optional display is also available to create a highly accurate, yet cost-effective hygrometer. As well as semi-conductor manufacture, the Pura range is also designed for fiber optic production, optical coating processes and industrial gas manufacturing applications.
