Online PH ORP Analyzer with Ground Electrode -2 to 16pH Range ±2000mV ORP for Water Treatment
The Online PH ORP Analyzer with Ground Electrode is engineered for precise monitoring in chemical processing and water treatment applications. This differential signal input gauge eliminates reference junction potential and sensor ground loop issues when used with ground rod pH sensors.
Utilizing salt-bridged primary battery electrodes (PH electrodes), the analyzer detects hydrogen ion concentration changes in solutions. The pH glass electrode measurement provides reliable readings with mathematical definition pH = -lg[H⁺].
- Water treatment monitoring: drinking water, surface water, groundwater, environmental sewage discharge, urban drainage networks
- Industrial process monitoring: chemical, petroleum, paper, food, pharmaceutical, electroplating, PCB manufacturing
