▋ Product Parameter

▋ Product Size

▋   Installation Method

1. Sensor use Sensor measurement needs to have a certain space, the bottom and around the need to retain more than 2cm spacing; It is recommended to install the sensor horizontally or to measure against the quasi-current direction. 

2. Sensor cleaning 

You can use warm water containing detergent or alcohol to clean the organic component dirt on the electrode; Mechanical cleaning will destroy the matte layer on the electrode surface. 

3. Calibration of sensor 

In order to ensure the accuracy of conductivity measurement, it is necessary to periodically calibrate the electrode constant using standard liquid. 

4. Equipment preservation
Before storage, clean the sensor and leave no residual water. The sensor should be stored in a dry environment.

▋ Application

▋ FAQ

1. Abnormal sensor reading:

It may be caused by sensor damage, sensor contamination and sensor deviation. You need to replace the faulty sensor or clean the debris attached to the sensor, or re-calibrate the sensor or replace the calibration fluid.

2. Communication failure:

Communication failures are mostly caused by data transmission problems when monitoring equipment communicates with host computers or cloud platforms. Generally, you need to check the connection line to check whether the communication interface and communication parameters are correct, and then reset the system.

3. Power supply failure:

Power supply failure refers to the insufficient or unstable power supply of the device, resulting in the normal operation of the device. To ensure the stability of the power supply, add a power filter to check whether the power supply and the circuit are normal.

4. Improper maintenance:

Before using the equipment, it is necessary to carry out daily equipment inspection, timely cleaning of the equipment, replacement of consumables and wearing parts to ensure the normal operation of the equipment. At the same time, regular maintenance of the equipment should be done to maintain the stability of the equipment performance.
