　　2. Introduction to SZ-YD online hardness tester products

　　The water hardness online measuring and controlling instrument adopts the water hardness selective electrode method (ISE method) imported from the United States, which has high sensitivity, rapid signal response, accurate measurement, stable performance, and simple maintenance. This measurement and control system has the characteristics of easy use, high accuracy, and economy. Using this series of analytical techniques to ensure the stability, reliability, and accuracy of the instrument's long-term operation. It has functions such as Chinese menu operation and 485 communication.

　　Used for continuous monitoring and control of water hardness content in drinking water treatment plants, canning plants, drinking water distribution networks, water quality treatment projects, etc.

　　Key Features:

　　◇ Large screen dot matrix LCD display, Chinese menu operation.

　　Simultaneous display of multiple parameters: water hardness value, temperature, output current, etc. are displayed simultaneously, which is intuitive and easy to read, and there is a range overrun prompt.

　　◇ There is a function to restore factory settings.

　　Communication function (optional): Equipped with RS-485 communication interface (partially compatible with MODBUS protocol), the hardness value corresponding to 4-20 mA current output can be set arbitrarily.

　　◇ Optoelectronic isolation 4-20mA current output.

　　Watchdog function: Ensure that the instrument panel does not crash.

　　◇ Power failure protection>10 years.

　　Chinese menu operation
