Compressed air hygrometer Superdew 3 WP

industrialwith LED displaywall-mounted

Overview
The Superdew 3 WP from Shaw Moisture Meters is a wall-mount, weatherproof (IP65 / NEMA 4X) inline dewpoint hygrometer designed for precise trace moisture measurement in process gases and compressed air. It provides durable protection against dust and water ingress for industrial environments.

Fast and reliable
Combining SHAW aluminium oxide sensor technology with digital electronics, the Superdew 3 WP delivers fast, repeatable dewpoint readings suitable for continuous process monitoring where trace moisture control is required.

Accurate
The instrument uses a SHAW ultra-high-capacitance aluminium oxide sensor offering superior stability and repeatability, with certified accuracy better than ±2 °C (±3.6 °F) dewpoint.

User configurable
Readings can be shown in °C, °F, ppm(V) or lb/MMSCF on a clear five-character LED display. Two independent, fully programmable alarm relays are provided and set points and parameters are adjustable via the front-panel keypad.

Flexible installation
The Superdew 3 WP includes an isolated 4–20 mA analogue output (adjustable span) and permits installation of the display/control unit up to 1,000 metres from the sensor, enabling flexible placement of electronics separate from the inline sensor.

Supplied ready to use
Each kit is configured prior to supply and includes the Superdew 3 WP instrument, a SHAW dewpoint sensor, a sensor holder and two metres of sensor cable for immediate installation and reliable long-term monitoring.
