Monitoring ionized water

I want to check the ionized water 24 hours a day.

For sensors, I want to use a list like this:

SEN0169-V2

SEN0451

SEN0464

Is it okay to use ionized water for about a year without calibrating the product?

What is the calibration cycle for the sensor? The product above is said to be usable for 24 hours a day, but I would like to ask if it can be used continuously in ionized water.

In the case of other companies' existing products, the sensor values ​​started coming out completely strangely after 2-3 months, making it difficult to measure.
