SMT50
The new SMT50 now available!
The SMT50 is designed and manufactured by TRUEBNER. It is a low cost FDR soil moisture sensor.
Compact, functional and robust: The PCB board based design allows for an economic design, and the blade shape facilitates installation. The casing and cable is water sealed.
The SMT50 has a broad measurement range. It is maintenance free and frost resistant. With short response times and low disturbance by salinity it is designed for a long term observation.
