Question

disadvantages of ph scale more than 3

Answer 1

One downside to using a pH meter is that the cost of the meter is significantly higher than using test strips. The pH meter is a long-term investment for gaining accurate results. For those who are going to be taking an occasional reading, test strips may be a better option. Another disadvantage in using a meter is that it needs to be cleaned regularly to avoid contamination. Most probes have a glass tip that may break or become damaged if exposed to corrosive chemicals. These are just a few considerations to think about before making a substantial purchase of a pH meter.
