Room Humidity Temperature Transmitter RHT-series

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.
