VeriDri is a low-cost dew point temperature or PPMv moisture loop-powered transmit- ter intended for OEM applications such as desiccant regenerative air or gas dryers, drying application for plastics prior to injection/blow molding, dryers for medical air and glove boxes. It has the features of thin-film aluminum oxide moisture sensor technology, microprocessor-based, all-digital technology for reliable operation, compact size, NEMA 4X/IP67, loop-powered 4 to 20 mA output, -110° to +40°C dew point tempera- ture/0 to 10,000 PPMv moisture (with constant pressure) overall range capability and NIST-traceable calibration.
The VeriDri moisture transmitter provides low‑cost, compact, loop‑powered measurement of dew‑point temperature and moisture for OEM dryer, medical air, glove box and other gas‑drying applications. It uses thin‑film aluminum oxide sensor technology and offers NIST‑traceable calibration for reliable performance.
Key specifications include a –110 °C to +40 °C dew‑point range, 0‑10 000 PPMy moisture range, 4‑20 mA output, 7‑28 VDC power, NEMA 4X/IP67 enclosure, and dimensions of 6.76 × 1.13 in. The device meets accuracy within three minutes of power‑up and responds to moisture changes in less than five seconds.
