PT1000 /PT100 Temp. Compensation PH Sensor For Wastewater

PT1000 /PT100 Temp. Compensation pH sensor for wastewater

Ph electrode reference junction blockage, electrolyte loss, glass bulb contamination, and use of the wrong calibration buffer can all lead to decreased electrode slope and performance. Temperature is also an important factor for electrodes. The potential of the electrode to measure the sample depends in part on the temperature of the sample. Compensation is possible because temperature is known to be linear to pH.

The accuracy of the measurement is affected by many factors, including the accuracy of the buffers during calibration, whether temperature compensation is used, whether the appropriate electrodes are used, whether there is sufficient time to measure, whether the correct endpoint and measurement mode are selected, etc. When these factors are fully taken into account, there is a slight error in the accuracy of the measurements.

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 5m by default, other lengths need to be customized, contact our customer service, the price will vary with the change of length.

5. How often must the pH sensor be calibrated?
A: Depends on the type of sample:
Dirty samples and non-aqueous samples require more frequent calibration.
Depends on the required accuracy:
For very accurate measurements, at least daily calibration is required.
Depends on the quality of the electrode:
Old electrodes require more frequent calibration.
