Since the battery 8 is an extra-low voltage power supply, the general output voltage is 3.7V power supply, so the boost conversion module 7 is used, and the power is supplied to the conductivity probe 6 after the voltage is boosted to 12V; the conductivity probe 6 is suitable for an instrument with a water temperature detection range and a range of 0-5000ppm; the boost conversion module 7 is connected to a remote transmission module 9 through a wire , the remote transmission module 9 is arranged in the box body 1; the boost conversion module 7 adopts the modbus communication protocol to connect with the remote transmission module 9 and receive the detection instructions at regular intervals; the remote transmission module 9 is responsible for sending data to the receiving end platform, the specific transmission mode is 4G, using a directional flow card, and the transmission protocol is MQTT; at the same time, the remote transmission module 9 is responsible for sending the timing detection instruction to the conductivity probe 6 to complete the detection of the fixed interval time, and the remote transmission module 9 has an antenna 10 arranged outside the medium, and the antenna 10 passes through the second light hole 4; the boost conversion module 7 is connected to a waterproof switch 11 through a wire, and the waterproof switch 11 is fixed on the third light hole 5; in view of the fact that most of the sites are pipeline inspection wells, all components inside the device are sprayed with waterproof paint, and all gaps outside the device are filled with glue. This application solves the difficulties of automatic monitoring of conductivity in the field, fills the gaps in water quality monitoring, and has the advantages of high-strength waterproof capability, unmanned automatic monitoring, and long replacement cycle of accessories; and the equipment can be directly connected to the receiving end platform, and with the help of the platform function, it can achieve early warning, alarm and trend analysis capabilities.

The more free charge carriers contained in the medium, the higher the conductivity and current. The resistance is calculated from the measured current according to Ohm's law. The conductivity is the reciprocal of the resistance. The present application sets an insulating tube 20 between the inner electrode 21 and the outer electrode 19 to prevent them from interfering with each other and improve the detection accuracy. The conductivity probe 6 is directly fixed on the box body 1, so that the structure is fixed and stable.
