Environment Monitoring Sensors Manufacturer
The industrial water PH sensor (RS-PH-*-2-*) is a device for measuring the pH value (hydrogen ion concentration index, pH) of a solution. With automatic temperature compensation function. It is suitable for industrial sewage, domestic sewage, agriculture, aquaculture, and other scenarios in a non-corrosive weak acid and weak alkali environment. The output signal has rs485, 4-20ma, 0-5V, 0-10V.
RS-PH-*-2-* industrial pH sensor adopts conventional composite electrode, which is suitable for the measurement of conventional sewage, tap water, environmental sewage, domestic sewage and other solutions. The pH measure range is between 0~14pH, and the resolution is 0.01pH. The adaptation temperature of the electrode is 0-80℃. This water pH sensor consists of two parts: a data collector and an electrode probe. The ph electrode probe has four lengths of 5m, 10m, 15m, and 20m. The housing of the data collector is IP65 protection grade, which can be used in outdoor rain and snow environment.
When it detects that the PH concentration exceeds the preset alarm value, it can provide multiple alarm methods such as interface alarm, sound and light alarm, SMS alarm, telephone alarm, email alarm, etc., to remind managers to troubleshoot the cause of excessive PH value in time, and record the event for information Call and analyze.

The output signal types of this industrial water PH meter are divided into RS485 and analog. The data collected by the RS485 industrial PH sensor can be connected to the environmental monitoring host through RS485 wiring, and then uploaded to the environmental monitoring cloud platform through the GPRS/4G signal output. Real-time monitoring is realized through the environmental monitoring cloud platform to ensure the safe discharge of industrial wastewater. In addition, the environmental monitoring cloud platform also has functions such as historical data analysis, viewing, exporting, and remote setting of data parameters, and supports multiple login methods on the computer terminal, mobile phone APP, and WeChat official account.
