TMC70 - Compact meteorological transmitter


The possibility of a real climatic change affecting the world economy, makes that authorities, organisms and society needs to know accurately the main atmospheric variables.

The compact meteorological transmitter TMC70 offers the ultimate solution for measuring in one only sensor: wind, temperature, humidity, barometric pressure, solar radiation and precipitation.


- Ultrasonic technology in the wind sensor.
- Doppler radar for precipitation.
- Compact body and easy installation.
- No moving parts, maintenance free.
- Integrated heating system.
- Optional internal GPS and compass.
- Data output are in RS485 with protocols MODBUS, NMEA-0183 or SDI-12.
