Accurate detection of trace levels of moisture has been a challenge to the process world owing to the fact that high concentrations of water are present in the atmosphere; approximately 1% by volume in room air. Teledyne Analytical Instruments is familiar with this challenge, having successfully developed one of the broadest lines of trace ppb / ppm O2 analyzers commercially available. In developing our trace O2 line, we have had to contend with the fact that 209,000 ppm of O2 is present in the atmosphere – ready to jeopardize the analysis of typically less than 1 ppm of O2. Teledyne is utilizing 50 years of expertise in detecting trace oxygen to produce a complimentary line of trace moisture analyzers – Series 8800.

The MP300 uses a thermoset, polymer-based, capacitive sensor measuring relative saturation. As a result, a change in sensor capacitance is directly related to change in relative humidity. The MP300 sensor offers fast response and resistance to contamination from glycols, amines, and sulfurs which makes the MP300 ideally suited for natural gas applications.
