STR120B Soil water potential meter
Host low power consumption design, Chinese liquid crystal display, real-time display of sensor data acquisition, current GPS position, battery power, alarm function, current date, storage capacity and amount of stored data, and can set the data storage interval.
Host internal FIash can store 30,000 pieces of data, standard 4G memory card unlimited storage.
Built-in 7.4v4ah lithium battery, with charging protection and low voltage reminder function.
Data view mode, you can view the data on the host or import it into the computer for view and analysis. The data saved inside the host will not be lost due to unexpected power failure.
The host can be connected to different sensors through the hub, without affecting each other's measurement accuracy. The host can be connected to 16 kinds of sensors at the same time, up to 32 sensors, and the sensor communication cable can reach up to 100 meters.
