Advantages Of The pH ORP Analyzer
1. The instrument has a clock function, which can move the time according to the year, month, day, hour, minute, and second, accurate to the second. It also records measurement data on time to form historical data that can be consulted. The instrument can record up to 14,000 historical measurement data, and the recording interval is freely set by the user. In addition, the user's maintenance operations on the instrument will also be recorded, and the last 100 maintenance data will be saved. When the instrument works abnormally, the user can use these data to find and analyze the cause.
2. The pH ORP meter water quality transmitter has the diagnosis function. When the instrument is calibrated or maintained, the sensor can be diagnosed. When the sensor is improperly operated or has poor performance, an image prompt will appear on the screen. It is recommended that the user should re-maintain or replace the sensor.





The pH ORP analyzer can be widely used in various industries.


Water treatment monitoring: Drinking water, surface water, water quality, groundwater, swimming pool, etc.


Industrial process monitoring and dosing control management: Chemical, petroleum, paper, food and medicine, electroplating, PCB manufacturing, etc.
