YUEPING PHS-3CB PH electrode with PHS-3CB acidity meter -2.00~19.99pH

I want to test the pH value of clear water samples, such as acid-base solutions in the laboratory, which Electrode should I choose?

E-201-C Electrode is a liquid-addable pH composite Electrode with a plastic shell, which is rugged and equipped with a low-noise Shielding line, which can effectively reduce measurement interference. Its fiber salt bridge and silver-silver chloride reference system, combined with 3mol/L potassium chloride external reference solution, are very suitable for measurement of clarified water samples and acid-base inorganic solutions, ensuring the Stability and accuracy of measurement results.

Our laboratory daily needs to measure the pH of some water samples, such as buffer or pure water. Why is this Electrode more suitable?

The YUEPING E-201-C Electrode is designed for clarifying water samples. Its reference system uses a fiber salt bridge and a 3mol/L potassium chloride solution, which provides a stable liquid contact potential. Response is fast and drift is small in low ionic strength water samples. At the same time, the plastic shell is resistant to corrosion, suitable for conventional acid-base solution measurement, avoids clogging or contamination problems common in clean water applications, and is very suitable for daily water quality analysis in laboratories.

When you say use it, do you just mean when I calibrate calibrate? Or do I have to turn it on when I measure the PH? Also, when I calibrate, no, turn it off when not in use. In addition, when I want to measure the PH, I also have to unscrew it, and then turn it off after the measurement, is that what you mean?

As long as you test the liquid, the red swirl/spin of your lid should be mouth-to-mouth, and you have to turn it off when you are not using it. Otherwise, its electrode will not flow out, and it will start that, and there will be no chemical reaction. Therefore, you should open it when you are using it, and turn it off when you are not using it.

PHS-3CB electrode, does this need to be activated? Use ph4 buffer, or saturated potassium chloride?

Potassium chloride

Do you have the electrodes required in the GB/T1545 standard?
