100～240VAC Two SPST Relays Online PH ORP Tester For Aquaculture Water Treatment
Brief introduction
ORP measurements are not controlled by temperature, so ORP electrodes do not require temperature compensation. In case the oxidation level is high (the ORP value is high), platinum electrodes are recommended, and conversely gold electrodes are recommended. Both inert electrodes are usually used as reference electrodes for ORP measurements.
The PH/ORP tester 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
Usually the PH tester can be connected to the ORP electrode to detect the redox charge of the aqueous solution and is usually labeled PH/ORP tester
Applications of Online PH ORP tester
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

Advantage of Online PH ORP tester
The PH ORP tester is an online tester with rich output configuration, suitable for high-demand monitoring and control applications.
All user-entered configurations are fixed for an unlimited period of time and data is not lost even without power. The output and control configuration are recorded in another configuration list for user find and inspection.
The PH ORP instruments are available in a variety of dimensions to meet a wide range of installation methods, while also providing the necessary installation accessories. The PH ORP tester intelligently diagnoses glass electrodes and prompts field engineers for electrode maintenance or replacement.
The PH ORP tester 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 instrument 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.
