1. Large screen dot matrix LCD display, Chinese menu operation.
Multi-parameter display simultaneously: ozone value, temperature, output current, etc. are displayed at the same time, which is intuitive and easy to read, and has a range over-limit prompt.
2. Restore factory settings.
3. Manual/automatic temperature compensation function.
4. Communication function (optional): It has RS-485 communication interface (partially compatible with MODBUS protocol), and the ozone value corresponding to 4~20 mA current output can be set arbitrarily.
5. Optical isolation 4-20mA current output.
6. The hysteresis can be set arbitrarily to avoid frequent switching of the switching relay, and there are setting switch off and closing functions.
7. Watchdog function: ensure that the meter will not crash.
8. The core devices are from famous foreign brands.
9. Power failure protection > 10 years.
