1. The salt sensor probe is inserted into the excavated soil and buried in the soil. Do not touch the graphite electrode of the salt sensor with a hard object to avoid damage.
2. In order to ensure the accuracy of soil salt measurement, the soil moisture is moderate and the graphite electrode can be tightly attached to the soil to determine the salt content in the soil.
3. Avoid removing the sensor during installation.

(1)if equipped with the collector produced by our company, we can connect the sensor directly with the corresponding interface on the collector by using the sensor wire.
(2) if the transmitter is purchased separately, the line sequence of the transmitter matching line is as follows:
Line color | Output signal | ||
Voltage mode | Current mode | Communication | |
Red | Power + | Power + | Power + |
Black (green) | Power ground | Power ground | Power ground |
