Industrial Online pH/ORP Meter WXZJ-PH8816 Zeju Online Acid-Alkali Detector

Industrial Online pH/ORP Meter WXZJ-PH8816 Online Acid-Base Detector Acid-Base Analyzer

Applications
Widely used in wastewater treatment, pure water, circulating water, boiler water systems, as well as online pH/ORP monitoring in process industries such as electronics, aquaculture, food, printing and dyeing, electroplating, pharmaceuticals, fermentation, and chemical engineering. It is highly effective in environmental monitoring and remote system applications, including surface water and pollution source discharge monitoring.

Main Features

◇ Large-screen dot-matrix LCD display, Chinese menu operation, multi-parameter simultaneous display.
◇ Automatic temperature compensation function.
◇ Communication function: Equipped with RS-485 communication interface (partially compatible with MODBUS protocol) (optional), convertible to RS-232. The 4–20 mA current output can be arbitrarily set to correspond to pH values.
◇ Optional PC-based online acquisition software for data collection and processing.
◇ Notebook: pH/ORP modes can each store 50 measurement data points, allowing users to record measurements as needed.
◇ Automatic recognition of standard solutions, restorable to factory settings.
◇ Watchdog function: Ensures the instrument does not freeze.
◇ Power-off protection >10 years.
