The QMR101 Precipitation Sensor is an economical and accurate rain gauge
made of plastic material which is highly resistant to UV-radiation and
even frostproof.
The QMR102 Precipitation Sensor is an aerodynamically shaped rain gauge
designed to minimize the wind originated airflow reducing the catch.
Manufactured from UV-radiation resistant plastic, making it a very
rugged instrument.
Vaisala Rain Detector DRD11A features fast and accurate precipitation detection (ON/OFF). The sensor operates via droplet detection rather than by signal level threshold. The capacitive principle utilizes the RainCap sensor plate.
This instrument uses a tipping-bucket mechanism to produce a contact
closure every time it receives a predetermined small quantity of
rainfall (0.2 mm). The body and funnel of the gauge are of aluminium
alloy.
