Product Name: PH pH meter calibration powder / liquid correction
Liquid open directly
PH pH standard solution preparation powder has 4.00, 6.86, 7.0, 9.18, 10.01 five specifications,
Each package can be formulated 250ML standards.
Cut plastic bag, pour the powder flask 250ML, a small amount of CO2-free distilled water bag wall, and diluted to scale shake well.
Powder shelf life of 2 years.
PH pH meter calibration buffer solution used directly
Calibration solution does not pollute the premise can be reused after the watered shelf life of about six months.
Calibration fluid use:
The pH meter electrode with pure water and clean (2-3 times), and then the electrode into the calibration solution which will be adjusted to pH meter PH value of calibration solution with the same value.
If you want some more precision instrument, you can two-point or three-point calibration.
The so-called two-point calibration, Calibration calibration solution is to use two sizes, three-point calibration calibration calibration solution is three sizes.
Usually start with 6.86 to start the calibration and then with 4.00 or 9.18.
In the following cases, PH meter recalibration necessary:
1. After calibration has been used (or place a long time);
2. Use the number of electrodes particularly frequent;
3. The measurement accuracy is relatively high;
4. When replace the electrode (for replaceable electrode pH meter)
