HDT Series

Reliable HDT Series Dew Point Transmitters

Real value and fits wide range of applications – loop-powered Aluminum Oxide Sensor Dew Point Transmitter

Based on years of dedicated research and development and proprietary scientific breakthroughs, our HDT Series has our HTF™ aluminum oxide sensor.

Our HDT Series dew point transmitters are designed as compact, simple and reliable instruments, which will continually monitor air dryer performance, compressed air quality and dry gas moisture, from ambient dewpoint levels to as low as -100°C.

The HDT Series dew point transmitter is a rugged and unique loop powered dew point meter capable of accurate and reliable gas and liquid hydrocarbon phase measurements.  It has a measuring range of -100ºC to +30ºC or -60ºC to +30ºC.

Customers can also request special ranges for special applications. Our dew point sensors provide a high degree of accuracy, speed, of response and stability unavailable from instruments using conventional aluminum oxide or polymer sensors.

The HTF™ aluminum oxide sensor is the product of years of intensive research and has been thoroughly field proven and performs better than other aluminum oxide moisture sensors on the market.  HTF aluminum oxide sensors are manufactured with high uniformity. Consequently, sensors are freely interchangeable without factory calibration or changing of EPROMS, as is required with conventional aluminum oxide sensors.
