18~36V Online PH ORP Analyser With Ground Electrode For Water Quality Control
The PH/ORP meter not only has the temperature detection and compensation function of the water sample, but also has the patented temperature detection and temperature drift compensation technology, which makes the instrument more stable and accurate in all kinds of environments.
The PH/ORP meter can be connected to a variety of traditional pH/T or ORP combination electrodes, and support differential signal input to meet the different needs of applications.
The differential signal input PH/ORP on-line controller is compatible with DRFN pH sensor with grounding electrode to solve the interference of a small amount of leakage in solution to the detection and can deal with more stringent PH/ORP measurement.
Applications of Online PH ORP meter
1 Water treatment monitoring: drinking water,surface water,ground water,environmental sewage discharge monitoring,urban drainage network monitoring.
2 Industrial process monitoring and dosing control treatment: chemical,petroleum,paper,food,medicine,electroplating,PCB manufacture.

The sensor has self-diagnosis function. When the instrument is calibrated and maintained, the PH/ORP sensor can be diagnosed. If the operation is improper or the characteristics of the PH/ORP sensor are not good, the screen will display the image and the buzzer will prompt briefly. Users are advised to maintain or replace sensors.
The PH/ORP online meter for differential signal input is compatible with ground rod pH sensors to solve problems like reference junction potential and sensor ground loops.
The PH ORP meter is an online tester with rich output configuration, suitable for high-demand monitoring and control applications.
