Digital ph tester

For those of you that are using one, how often do you find you need to calibrate it? I've been doing it every time I start a new mash. Just curious what is really necessary.

I check it about every six months. It comes with some calibrated powders and u can get new ones at the pool store

It should be re-calibrated at each use.

Thanks you guys. Looks like I'll continue with what I've been doing.
