The Michell Pura trace moisture transmitter measures down to -120 ?Cdp (-184 ?Fdp), equivalent to 1 ppbV, making it suited to ultra-high-purity gas applications such as semiconductor and specialty gas production. It provides stable, repeatable measurement with a fast response, and communicates via a 4?20 mA 2-wire output and Modbus RTU over RS485, with an optional monitor/controller available. Process connections are 1/2″ and 1/4″ male VCR, with MiniDIN 43650 C and M12 electrical connectors and optional hazardous area approval. A traceable 7-point calibration certificate is supplied as standard, and the service exchange programme keeps maintenance straightforward.
