The new Superdew 3 WP wall-mount, weatherproof dewpoint hygrometer sets a new benchmark for accurate, reliable trace moisture analysis in process gases and dry compressed air. It delivers dependable dewpoint readings wherever precision matters most, even in harsh industrial environments.

Built for industrial reliability
Engineered for demanding applications, the Superdew 3 WP features a robust, high performance, inline design housed in a durable, weatherproof enclosure. Its IP65 (NEMA 4X) rated protection shields sensitive components from dust and moisture ingress, enabling continuous operation and consistent reliability across industries from compressed air drying to industrial gas production and processing.

Proven dewpoint sensing technology for trace moisture
Superdew 3 WP incorporates Shaw’s unique AutoCal (automatic calibration) feature, allowing users to check and adjust the span of the dewpoint hygrometer in situ without special equipment. By briefly exposing the SHAW dewpoint sensor to a moisture level above its operating range (often ambient air), AutoCal verifies and, if necessary, corrects the instrument response, helping to maintain optimum accuracy between laboratory calibrations, reduce downtime and minimise calibration costs.

AutoCal – in-situ automatic calibration
At the core of every Superdew 3 WP dewpoint hygrometer is Shaw’s advanced dewpoint sensing technology, combining proven field performance with modern digital electronics for precise trace moisture measurement. The dewpoint sensor consistently delivers exceptional accuracy, reliability and long-term stability. Shaw calibration engineers individually calibrate each dewpoint sensor to achieve system accuracy of ±2 °C (±3.6 °F) dewpoint and each instrument includes a Certificate of Calibration traceable to National and International Humidity Standards (NPL), ensuring confidence in measurement integrity and product quality.

Easy to use
The Superdew 3 WP dewpoint hygrometer offers full configurability to suit diverse trace moisture measurement needs. Users can switch between °C dewpoint, °F dewpoint, ppm(V) or lb/MMSCF on a clear, five-character LED display. Two fully programmable alarm relays provide early warning and process control, while the intuitive front panel keypad simplifies setup and operation for maximum efficiency.

Flexible installation
To ensure seamless integration into existing dewpoint and trace moisture monitoring systems, the dewpoint sensor can be mounted up to 1,000 metres from the Superdew 3 WP display. This allows optimum sensor placement within complex layouts while keeping the wall-mount, weatherproof hygrometer accessible for operators.

Ready to use trace moisture measurement solution
Shaw Moisture Meters supply the Superdew 3 WP dewpoint hygrometer as a complete, ready-to-install trace moisture measurement system. Each kit includes the Superdew 3 WP, SHAW dewpoint sensor, sensor holder and two metres of cable, configured precisely to suit your application requirements.

Reliable, accurate and built to last, the Superdew 3 WP wall-mount, weatherproof dewpoint hygrometer combines precision engineering with trusted SHAW sensor technology to deliver the performance, flexibility and confidence that industrial professionals demand in trace moisture measurement..
