Product Description

RK520-02 Soil Moisture Sensor, Temperature Probe& EC Sensor

RK520-02 Soil Moisture, Temperature & soil EC Sensor is integrated the moisture, temperature & EC measurement, offering real-time data on soil moisture, temperature, and electrical conductivity (EC). Ideal for precision farming, horticulture, and environmental research, this sensor enables efficient water management, crop health monitoring, and soil quality assessment. The stainless steel probe is inserted into soil surface or soil profile to test quickly. This soil moisture temperature and electrical conductivity sensor with temperature compensation to ensure the accuracy of measurement. The probe can be permanently embedded underground and be connected to a data logger for unlimited testing.
