main features

Adopting imported components and residual chlorine film heads.

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

Simultaneous display of multiple parameters: residual chlorine value, hypochlorous acid value, pH value, temperature, output current, etc. are displayed simultaneously, which is intuitive and easy to read, and there is a prompt for exceeding the range.

◇ There is a function to restore factory settings.

◇ Manual/automatic pH compensation function and temperature compensation function.

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

◇ Optoelectronic isolation with 4-20mA current output.

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

The core components are all from well-known foreign brands.

◇ Power failure protection>10 years.
