Description
The RHT is a indoor humidity and temperature transmitter which measures the humidity and temperature of air.
The RHT converts the measurements into standard signals of 0-10 Vdc or 4-20 mA.
Available with or without display indicating both Temperature and Humidity on one display.
Ranges and humidity parameters are selectable via dip switches.

E-paper Display

The display show the actual value of each parameter, Humidity (rH) + Temperature (T).
The display is an E-Paper display that reflects light just as regular paper, therefore the display is a passive (non-luminating) display.
Thin, light, flexible, good contrast, low energy consumption and no light reflections.
Easy reading even with high ambient brightness.
E-Paper displays only need energy when the display contents change.
Optics and readability are significantly better than with monochrome LCD´s or other bi-stable systems.
High readability independent of the reader's perspective.
