Why choose A200ISM?
- High scalability wide range detection: contains multi-parameter wide range measurement as standard, and detecting factors can be extended and modified as necessary to satisfy a variety of monitoring requirements.
- Smart control, simple upkeep and use: password security, a bilingual interface, and menu guidance. Self-cleaning electrode contacts reduce the need for human upkeep.
- 4–20 m: reliable transmission and stable anti-interferenceIn industrial settings, an isolated output and optional RS485 interface work well to keep electromagnetic interference out.
- It can work steadily in a wide range of difficult temperature and humidity conditions, and its working temperature adaption range is wider.
Featured Applications
- Power industry: online monitoring and process control of water quality parameters such as circulating cooling water for power plants, boiler feedwater, and thermal system water
- In the field of pharmaceuticals and chemical engineering, monitoring of water quality standards for pharmaceutical production process pure water, chemical reactor inlet/outlet water, and chemical circulating water
- Food industry: online detection of water quality safety for food processing production water, beverage preparation water, and food cleaning water
- Other industrial fields: Continuous measurement and control of water quality for electronic semiconductor pure water, printing and dyeing textile wastewater, paper industry circulating water, etc

Daily maintenance and precautions
- To get rid of dirt and oil, clean the electrode sensing surface often. Stay away from things that could make the detection less sensitive.
- To make sure that the measurement data is correct and stable, you should calibrate the sensors based on the water quality at the site on a regular basis.
- The electrode cord needs a particular wire that can’t be used on its own to work. It is recommended that the longest length not be more than 30 meters.
- Make sure you turn off the power before you clean, wire, take apart, or do anything else to your equipment so it doesn’t get broken.
- Check your tools often to aCheck the wiring on the equipment often to make sure it’s safe. Don’t use it in regions where there is a lot of sunlight, heat, or corrosion.make sure they don’t rust or vibrate, which could limit their life.
