Attention:

1. The electrode is a consumable product. after use, the diaphragm begins to show signs of aging. It must be calibrated every 1 month to ensure measurement accuracy. If the electrode has been purchased for more than 6 months, please pay attention to replace the electrode.
2. The electrode installation environment requirements are: water pressure less than 0.15MP, flow rate less than 10cm3 / s, temperature less than 35 ℃.
3. Regularly check the electrode head for dirt adhesion. If you need to clean the electrode, rinse the dirt with water as much as possible. Do not touch the diaphragm with hard objects, causing the diaphragm to break.
4. There is a white spot about 1cm above the electrode diaphragm. Make sure that the white spot is immersed in the water body, and the white spot cannot be damaged or attached with dirt, otherwise it will cause electrode damage or inaccurate measurement data.

Common Questions:

1. The warranty period of hardness tester and ion tester is 3 months.
2. The hardness tester is a soft film, which is easily affected by water flow, has poor repeatability, and the zero position is easy to convert. regular calibration is required to improve accuracy.
3. The purchased hardness tester will not be used until half a year after it is received. The measurement data is not accurate or has no value. Our hard
The warranty period of the meter and ion meter is three months. the receipt of the goods begins, and it is not used after three months. the electrode problem is not covered by the warranty.
4. The measurement data fluctuates. generally, it is caused by submerged installation and water flow attenuation pressure rotation. It is recommended to use circulation
The electrode is installed in the tank.
5. The measured value is not accurate. after receiving the hardness tester or ion meter, there is an error between the measured value and the standard solution.
In the standard solution, the instrument is energized for one day, and the standard solution is re-measured the next day, and if not allowed to re-calibrate.
6. There is an error between the hardness tester and ion meter measurement data of the water sample and the data detected by the third party. There may be other ions in the water sample.
It is recommended to use local water samples for calibration.
