DZZH DZZM Type Automatic Meteorological Stations

The DZZH type and DZZM type automatic meteorological stations are solid, reliable system without moving parts and in conformity with the four factors of all solid state wind speed, wind direction, temperature and atmospheric pressure, of which, the measuring of wind speed and wind direction is based on the proprietary technology of "Thermal Field Variation". The parameters of wind speed and wind direction are obtained by wind blowing a heating cylinder and cause the thermal field around the cylinder changed.

The DZZH type and DZZM type automatic meteorological stations can precisely and quickly respond the changes of wind and has threshold of zero starting wind velocity. There is no bearing or potentiometer in the sensor, so no erosion or wearing can be influenced, at the same time the automatic heating system is built in the meteorological station, it can not be frozen. The DZZH type can be used for marine platform or station with marine climate owing to adopt special materials on its outer shell and antiseptic treatment; the DZZM type can be used in severe condition and heavy polluted environment besides using on common weather station.
