Online pH Sensor
The S‑pH004 online pH sensor uses an electrochemical principle, employing a linear combination of a measuring electrode and a reference electrode that are sensitive to changes in the pH value of the medium to measure the pH value.
The sensor uses a replaceable industrial‑grade electrode core and can support various types of pH probes, such as ultrapure water, high temperature, low temperature, desulfurization and denitrification, and hydrofluoric acid resistant probes.
It features temperature compensation , enabling temperature adjustment and digital signal conversion, RS485 output , standard MODBUS RTU protocol, and supports networking with various terminals .
