ON-WALL- HUMIDITY- AND TEMPERATURE SENSORS AFTF–MB
Calibratable outside humidity and temperature sensor AFTF, detect the
relative humidity (0…100% RH) and the temperature (–35...+80 °C),
including various parameters in the humidity measurement. Applied in
clean air and non-aggressive, dust-free environment. With a Modbus
connection in a resistant IP65 plastic housing and M20 cable gland for
cable connection, with quick-locking screws and an exchangeable plastic
sinter filter. International SI units (default) can be changed to
imperial (via Modbus).
