Easidew Transmitter 2-Wire Dew-Point Transmitter.

The Easidew TX Transmitter is a complete hygrometer designed for ease of use, incorporating all the features needed to make installation and operation as simple as possible.

Dew point (water vapor condensation temperature) measurement is made easy with this calibrated transmitter that can be quickly incorporated into your air or gas management control system. The Easidew TX Transmitter is connected in a 2-wire loop powered configuration. Its rugged construction makes it well suited for industrial applications. Weighing only 5.3 oz., it is light enough to be supported directly by its sample tubing without additional mounting brackets.
