Dewpoint Transmitter


Kahn Instruments, Wethersfield, CT, has announced the new Easidew PRO I.S. Dewpoint Transmitter. The Easidew PRO I.S. is a ruggedized version of the intrinsically safe Easidew I.S. Transmitter and is designed for continuous measurement of moisture  content of gases in hazardous area applications typically found in natural gas, petrochemical and process industries. Key features include:

  • Heavy duty, process type NEMA 4 / IP66, weatherproof stainless steel housing with ˝” NPT conduit entry fitting

  • FM/CSA certified for Class I, Div. 1, Groups A, B, C, & D T4 hazardous location use

  • 2-wire, loop-powered, 4-20 mA linear, analog output

  • Output configurable in °F or °C dewpoint or PPMv moisture content (0-100, 0-1000 and 0-3000 PPMv ranges)

  • Operating pressure up to 5000 PSIG

The Easidew PRO I.S. Transmitter has a dewpoint measurement range of -148°F to +68°F, accuracy of ±3.6°F and operates from any 12 to 28 VDC power source. The instrument also features field adjustable, resettable failure modes for Over Range, Under Range and Sensor Fault conditions, and temperature compensation.


The Easidew PRO I.S. Transmitter is economical to purchase, install and maintain. Installation costs are minimal, because of the transmitter’s ruggedness, small footprint and simplicity. Ongoing operating costs are low, because the Easidew PRO I.S. is reliable and durable. Only periodic re-certification is required to maintain calibration accuracy. Kahn even offers an exchange program, so a customer’s process is never out of operation.
