Featured Applications
- Municipal water management includes keeping an eye on the whole process at water plants, as well as the process sections and discharge outlets of sewage treatment facilities.
- Industrial manufacturing: controlling the flow of water, boiler water, and clean water in the electronics, power, and chemical industries.
- Life and Health: Checking that the quality of production water and process water in the food and beverage and pharmaceutical industries meets standards.
- Environmental supervision: keeping an eye on and notifying people about surface water, river reservoirs, and industrial park discharge outlets online.

Daily maintenance and precautions
- The electrode detecting surface should be cleaned often to get rid of oil and other debris, depending on how unclean the water is. The level of sensitivity to data will stay high.
- Regular calibration: To maintain measurements accurate, they should be calibrated based on how often they are used at the site.
- You should either retain the electrodes in a protective solution or let them dry once you turn off the machine.
- Make sure the power is off before you clean, install, or take apart the equipment.
- Check your tools often to make sure they don’t rust or vibrate, which could limit their life.
