GEC-pH485 digital sensor is a new generation of intelligent water quality detection digital sensor independently developed by our company. Without the host, directly measure the pH value and temperature value in the solution , and send output 4-20mA signal to the back-end equipment. It can also be connected to RS485 interface, and connected to the computer through MODBUS protocol for monitoring and recording.
★ Direct output RS485 or 4-20mA
★ Automatic temperature compensation
★ Remote setting parameters and calibration electrode
★ IP68 protection grade
GWQ pH sensor widely used in continuous monitoring of PH value or ORP value and temperature in solutions such as thermal power, chemical fertilizer, metallurgy, environmental protection, pharmaceutical, biochemical, food and tap water .
We have the pleasure of introducing ourselves to you as a professional factory in the export of water quality analyzer, Our activities cover a wide range of commodities, such as ph meter, dissolved oxygen meters, conductivity meter etc. Our products are superior in quality and moderate in price and are sure to be saleable in your market. We have been engaged in the water quality measurements business with many countries for many years. And in a very good position to supply most grades of ph meter at competitive prices and for good delivery.
GEC-PH485 digital ph sesnor is our hot selling sensor.
If you have any questions, please contact us▼.
In addition to ph485 sensors, we also have common ph sensor, matching controller, to achieve pH online measurement ,The composite electrode, PTFE electrode, glass electrode is popular.（ We provide a variety of pH sensors, ORP sensors, DO sensors, EC sensors, and TDS sensors. Please tell me your requirements, and we will recommend appropriate sensors for you！）
