PT1000 - 10 ～ 150℃ Online PH ORP Gauge With Ground Electrode For Chemical Processing Water Treatment
Brief introduction
The PH/ORP gauges has temperature detection and temperature compensation function, supporting pH electrodes with temperature to measure temperature changes in aqueous solutions. It is a patented temperature drift compensation technology, which makes the instrument more stable and accurate in all kinds of environments.
The PH/ORP gauges use salt-bridged primary battery electrodes (PH electrodes) to detect changes in the concentration of hydrogen ions in the solution, which affect the electrode level. It is usually made of glass and commonly known as PH glass electrode measurement. Mathematic defines pH as a commonly used congenital negative value for the concentration of hydrogen ions, i.e. pH=-lg[H⁺]
Applications of Online PH ORP gauge
1 Water treatment monitoring: drinking water surface water quality groundwater environmental sewage discharge monitoring urban drainage network monitoring
2 Industrial process monitoring and dosing control treatment: chemical petroleum paper food medicine electroplating PCB manufacture

Advantages of Online PH ORP gauge
PH/ORP gauge can be connected to a variety of traditional PH/T or ORP combination electrodes. It has the patented temperature detection and temperature drift compensation technology
The PH/ORP online gauge 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 gauge works accurately in years, months, dates, hours, minutes and seconds, it records the measurement data on time to form a consultable historical data. The PH ORP gauge can record up to 14,000 historical measurements. The recording interval is freely set by the user. User maintenances are also recorded and the last 500 maintenance data are saved to help us find and analyze the cause of the instrument's abnormal operation.
