The Easidew Online Hygrometer has been designed to make
continuous measurement of the dew point in air and gases
simple and reliable. The 1/8 DIN display unit is connected to the
Easidew Transmitter sensor module, which may be permanently
installed in a plant or process location at a distance of up to
800m (2625 feet) from the display. An analog output is provided
for re-transmission to a chart recorder or data-logger. The two
alarm relays are adjustable from the front panel and can provide
control of the monitored process. The Easidew Online can be quickly
incorporated into your air or gas management and control
system reducing the cost of ownership.
