Chinese display, Chinese menu, Chinese notes: The entire operation steps are prompted in Chinese and can be easily completed without the need for an instruction manual.

● Multi parameter display on the same screen: Display ORP value, input mV (or output current), temperature, time, and status on the same screen.

Historical curve: automatically stores measurement data every 5 minutes, and can continuously store ORP values for one month.

● Notepad function: The notepad faithfully records the operation and usage of the instrument and the time of alarm occurrence, making it easy to manage.

Monitoring electrode function: The method, time, and results of each calibration are recorded for easy retrieval and analysis of electrode variation patterns.

Digital clock function: provides time reference for various functions.

Conversion to 25 ℃: A 25 ℃ reference temperature conversion was performed on pure water and ammonia added ultrapure water, achieving the display of pH values at 25 ℃, which is particularly suitable for measuring various water qualities in power plants.

● Instrument stability without crashing: The watchdog program ensures that the instrument works continuously without crashing.

● Manual current source function: It can check and set the output current value arbitrarily, making it convenient to detect the recorder and lower computer.

● Software setting current output mode: The software selects either 0-10mA or 4-20mA output.
