Industrial water ph sensor

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.

About industrial ph sensor

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.

1.Submerged type: the lead of the pH electrode is threaded out of the stainless steel tube, and the 3/4 thread on the top of the pH electrode is connected to the stainless steel 3/4 thread with a raw material tape. Make sure that no water enters the top of the electrode and the electrode wire.
2. Sidewall: The manufacturer provides a 316L all-stainless steel sheath with a bevel, and the pH electrode can be screwed into the sheath.
3. Duct mount: Connect to the pipe through the 3/4 thread of the pH electrode.
