14pH Accurate PH Meter For Water Treatment And Industrial Process
DRFN’s pH meters are precise instruments for the measurement and control of pH and mV (ORP). Two output relays are provided on the pH controllers for close/open control. There are three types of electrodes for the meter, namely the pH glass electrode, pH antimony electrode, and the ORP electrode.
Introduction Of The PH Meter
-
2 high-precision 0/4~20mA current output;
- 2 settable SPST multifunction relays;
-
A two-wire RS485 interface;
- 128*64 large screen graphic dot matrix LCD screen;
- The protection grade of the housing is IP66;
-
Shortcut keys to perform necessary daily maintenance without entering the menu;
-
Menu passwords can be set for easy hierarchical management;
-
Power off protection, indefinite retention of parameters;
-
The communication protocol is Modbus RTU.

Advantages Of The PH Meter
1. The user can choose whether the displayed data is timely response or smooth response by adjusting the display rate according to observation habits.
2. The pH meter has a temperature compensation function, which can not only compensate the temperature of the test sample through the temperature sensor but also detect the working temperature of the instrument. When the working temperature of the instrument changes, it compensates for the hardware changes due to temperature drift. This patented technology makes the test results more accurate.
Applications Of The PH Meter
Water treatment monitoring: Drinking water, surface water, water quality, groundwater, swimming pool, etc.
Industrial process monitoring and dosing control management: Chemical, petroleum, paper, food and medicine, electroplating, PCB manufacturing, etc.
