IP68 Online Digital pH Sensor for Sewage Plant

Monitoring of pH value is a very important measurement item in sewage plants. In daily sewage testing projects, pH value is carried out as a routine test. Continuous real-time monitoring of pH value in sewage plants is very necessary, because the pH of sewage will affect the living environment of microorganisms in activated sludge. The large changes in pH value in sewage are also one of the indicators for judging environmental factors. Compared with analog pH sensors, the DPH790 online pH sensor uses a reliable and interference-free digital signal. It has built-in RS485 communication, which can convert the sensor's own measurement signal from an analog signal to a digital signal, ensuring that it can operate in long-distance cable runs and areas where interference may occur. In addition, the advantage of digital sensors is that they do not require a transmitter and can be directly connected to other industrial control equipment such as PLCs, computers, and data loggers to obtain data…
