1、 Product Introduction:

The PHS-80C online acidity meter has the characteristics of Chinese menu operation, high stability, superior repeatability, and multifunctionality. It can accurately measure the pH value, oxidation-reduction potential (ORP), and temperature value in a solution. Guang Fan is used for online detection of pH values in solutions such as environmental protection, sewage treatment, thermal power, aquaculture, food processing, printing, metallurgy, pharmaceuticals, fermentation, chemical engineering, and tap water.

2、 Main features:

Large screen dot matrix LCD display, Chinese and English menu operation, multiple parameters displayed simultaneously.

Optional automatic temperature compensation function

High limit alarm, low limit alarm dual relay, hysteresis can be freely adjusted

Communication function: Equipped with RS-485 communication interface (partially compatible with MODBUS protocol, optional), capable of converting to RS-232. The pH value corresponding to the 4-20 mA current output can be set arbitrarily.

Voice alarm controllable switch, set on or off through interface options

LCD backlight can choose energy-saving mode and automatically turn off at regular intervals

The core components are all from well-known foreign brands.

Password can be set to prevent accidental operation by non professionals
