PH Probe With 0~100℃ Working Temp. For Surface Water

pH probe with 0~100℃ working temp. for surface water

Our factory uses a special glass probe that is sensitive to pH on the measuring electrode. It is made of special glass that can conduct electricity and penetrate hydrogen ions. It has the characteristics of high measurement accuracy and good anti-interference. When the glass probe comes into contact with hydrogen ions, a potential is created. Potentials were measured against a reference electrode with a silver wire suspended in a silver chloride solution. The pH value is different, and the corresponding potential is also different.

It is converted into a standard 4~20mA output by the transmitter.

FAQ

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

2. How is this glass pH electrode composed?
A: The pH electrode is usually composed of an indicator electrode and a reference electrode.

3. 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

4. What is the wire length of the pH electrode?
A: The lead wire of this electrode is 3m by default, other lengths need to be customized.
