SHAW Model AcuDew high performance dewpoint transmitter. A new, robust and reliable, 2 wire, 4-20 mA loop powered transmitter.

Utilising the ultra high capacitance SHAW moisture sensing technology, the AcuDew offers superior sensitivity, accuracy, repeatability and speed of response.

This dewpoint transmitter incorporates the SHAW AutoCal feature, thereby allowing users to check the span of the instrument and correct for any deviation between annual laboratory calibrations. Notably, AutoCal can be carried out in situ and without the need for skilled personnel or special equipment.

Various dewpoint ranges are available covering an overall range from -120 °C to +20 °C (-184 °F to +68 °F) dewpoint and output units are configurable in °C dewpoint, °F dewpoint, ppm(v), ppb(v), g/m³ and lb/MMSCF.
