PH/ORP Digital Water PH/ORP Potential Value Sensor Electrode Probe

DRFN online digital pH sensor, industrial online digital pH sensor is a new generation of intelligent water quality detection digital sensor independently developed by our company. The industrial online digital PH sensor can be used for data viewing, debugging, maintenance, etc. through the mobile phone APP or computer. It has the characteristics of easy maintenance, good stability, good repeatability and multi-function, and can accurately measure the pH value and temperature value in the solution.

It is widely used in wastewater treatment, pure water, circulating water, boiler water and other systems, as well as PH value detection in electronics, aquaculture, food, printing and dyeing, electroplating, pharmaceuticals, fermentation, chemical industry and other fields. Powerful functions in system applications.

Digital pH adopts industrial online electrodes, and the front end of the electrode is a flat structure, which is easy to clean. The built-in temperature sensor can automatically compensate the temperature, which is suitable for online long-term monitoring environment.

The digital pH sensor adopts RS485 output and supports Modbus, which can realize networking and system integration without a controller. Not affected by transmission distance, better stability, built-in temperature sensor, automatic temperature compensation, digital sensor, RS-485 output, support MODBUS.

FAQ

1. What is the measurement principle of this pH electrode?
A: The pH value potentiometric method uses the potential difference of glass electrodes for pH measurement.

2. How to judge the pH of the solution?
A: If the internal hydrogen ion concentration of the pH glass bulb is lower than the outside, the measured solution is recorded as acidic and the pH value is lower than 7; if the two are the same, the solution is neutral and the pH value is equal to 7; if the internal hydrogen ion concentration is higher than externally, the measured solution is alkaline and the pH value is higher than 7.

3. What is the wire length of the pH electrode?
A: The lead wire of this electrode is 1 m by default, other lengths need to be customized, contact our customer service, the price will vary with the change of length.
