Model 5812 Moisture Analyzer

Model 5812 Moisture Analyzer

Measuring moisture in natural gas is not a difficult application, but reliably measuring on a continuous basis is. Glycols and entrained compressor oils can quickly contaminate or damage most moisture sensors. In addition, many moisture analyzers have no means to detect the presence of such contamination, leading to inaccurately monitored or completely unmonitored gas streams.
