Product Description

Product Description:

DPH-220 is a basic type conventional water quality monitoring digital pH sensor, using industrial online electrode, and the electrode can be replaced, the electrode is designed as a spherical structure, compared to the flat structure increases the measuring contact area, the response speed is fast, the measurement is more accurate. Built-in temperature sensor, can be automatic temperature compensation, suitable for online long-term monitoring environment use.
Features:
1. Digital sensor, direct output of Rs-485 digital signal, support MODBUS/RTU
2. Built-in temperature sensor for automatic temperature compensation
3. Double salt bridge, double high impedance design, strong anti-interference, data stability
4. 3/4" NPT up and down mounting thread design for easy installation
5. Low sensor power consumption, internal circuit anti-interference design
6. Electrodes can be replaced, support complex water applications, support electrode customization
Scope of application:
Online monitoring of river water quality, industrial wastewater, environmental water treatment, food and beverage, fermentation, etc.
Note: Different fields of application, according to high temperature, high pressure, strong acid alkali, corrosive media, etc. need to choose different characteristics electrode probe
