Industry Online PH Analyzer For Waste Water Real-Time Monitoring
The pH sensor is a composite electrode composed of a glass indicator electrode and a reference electrode.
Stable data, reliable performance; simple installation. It is widely used in sewage treatment plants, water plants, water supply pipe networks, surface water, various industrial production process water and wastewater treatment processes, and pH online monitoring in aquaculture and other industries.
The configured controller can feel the data measured by the sensor in a humanized way, and the user can also configure and calibrate the interface of the controller to achieve 4-20mA analog output, realize relay control and digital communication and other functions.

Q1. Does the instrument have a self-diagnostic function and how does it prompt?
A: The pH meter has self-diagnosis function.When the instrument is in calibration and maintenance,it can diagnose the PH/ORP sensor,if there is improper operation or poor PH/ORP sensor characteristics, the screen makes an image display and advises the user to re-maintain or replace the sensor.
Q2. What are the special advantages of the pH instruments?
A: The instrument can not only compensate the temperature of the test sample by connecting the temperature sensor, but also self-check the working temperature of the instrument in real time. When the working temperature of the instrument changes, the instrument compensates the hardware change caused by the temperature drift. Make the test results more accurate, this is a patented technology.
