DEWPOINT MEASUREMENT SENSOR

The HPR200M hygrometer enables the air dewpoint to be controlled as it exits the pressurisation cabinets.
 
This measurement determines the overall operation of the cabinets, and prevents low quality air (moisture-loaded) from being injected into the cables.
This can be very easily fitted to any type of cabinet.
