Online PH/ORP Monitor WXZJ-280

Features Chinese menu operation, high stability, excellent repeatability, and multifunctionality. It accurately measures the PH value, oxidation-reduction potential (ORP), and temperature value in solutions. Widely used for online detection of PH values in solutions such as wastewater treatment, thermal power, aquaculture, food processing, printing, metallurgy, pharmaceuticals, fermentation, chemical industry, and tap water.

Product Features:

1. Large-screen dot matrix LCD display, Chinese menu operation, simultaneous display of multiple parameters

2. Automatic temperature compensation function, compensates for PT1000

3. Equipped with RS-485 communication interface (partially compatible with MODBUS protocol) (optional)

4. Notebook: PH/ORP modes can each store 50 measurement data

5. Automatic recognition of standard solutions, factory settings can be restored
