APX1-G2 pH ORP controller introduction
3 year ago
The Advantages of differential signal pH controller is that it can eliminate problems such as electromagnetic interference and electrode polarization, thereby improving the measurement accuracy and stability of pH value. The industrial online pH orp controller can be connected with the pH sensors and ORP sensors to monitor the water quality online in real time. In some special occasions such as power plants, the requirements for controllers and sensors will be different. Daruifuno's APX1-G2 pH meter is a controller suitable for special occasions. It not only has an automatic temperature compensation function but also has a 25°C conversion function, and supports the connection of solution ground pH sensor to prevent interference caused by leakage and make the measured value more stable and accurate.
Suzhou delfino environmental technology company focuses on online water quality analyzers, such as PH/ORP analyzer, Conductivity Analyzer, Turbidity Analyzer, Cod Analyzer, Dissolved Oxygen Analyzer, etc..If you are interested in the pil in Water Analyzer, please contact us.
