Can a PH meter be calibrated if the calibration solution is not one specifically provided by the manufacturer?
Yes, some pH meter manufacturers require users to prepare it themselves
There’s absolutely no problem; it can be prepared by oneself.
I learned about it. I didn’t know about PH calibration before; I thought it had to be done by the manufacturer. I saw it for myself today
Find a laboratory technician in a company to prepare the standard solution, and then calibrate it following the steps outlined in the instructions.
It can be prepared by oneself; there are specialized reagents available for the commonly used calibration solutions with pH values of 6.86, 4.01, and 9.18 – these should be available in the factory’s laboratory. Just have the lab staff prepare it.
Mainly, the distilled water needs to be boiled and then cooled to the specified temperature, with its volume having to be precise. The medications are packaged in small pre-weighed bags; the packaging bags should be washed twice with water to prevent residual medication from affecting accuracy ； The prepared solution should be stored in a sealed container and not for an extended period of time. If you pay attention to these, there will be no problems.
Yes, the manufacturer itself recommends that users prepare it themselves; just follow the instructions provided.
First, prepare it yourself, then use a gauge with high accuracy to test it, and subsequently use this solution as a standard.
As long as it meets the verification requirements, it’s fine
