1. Chinese display, Chinese menu, Chinese notes: The entire operation process is prompted in Chinese, and there is no need for an instruction manual, making it easy to complete.

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

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

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

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

6. Digital clock function: Provides a time reference for various functions.

7.25 ℃ Conversion: 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.

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

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

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

11. Four calibration methods have been added: manual input of zero point E0, slope S, and known pH value calibration have been added to meet the needs of customers in various situations.
