The Michell Pura ultra-pure moisture hygrometers are designed for trace and ultra-trace moisture measurement in high-purity gases, measuring down to -120 ?Cdp (-184 ?Fdp), equivalent to 1 ppbV. They deliver stable, repeatable readings with a fast response and can output dew point or moisture content over 4?20 mA and Modbus RTU over RS485. Available as both economical and advanced monitor solutions, they offer 1/2″ and 1/4″ male VCR process connections, MiniDIN 43650 C and M12 electrical connectors, and optional hazardous area approval. Each unit is supplied with a traceable 7-point calibration certificate and is backed by the Michell service exchange programme.
