pH Calibrating your ph meter.

[Sizzle Lips]

Its funny how many people I talk to about calibrating their ph meter that dont have a clue about what i am talking about......I have ph solutions and make it a practice to do a 3 point calibration check 2 times a year.......once a year is probably okay but I would sooner be safe than sorry.
Does anyone else make sure their meters are in check and clean...and how often do you calibrate..

Honestly, that's a scary freakin' thought, lol

I probably only use mine 3 or 4 times a year, and I clean it before and after each use. I also have 4.0 and 7.0 buffer solutions I use to calibrate it before I use it each time. Storage solutions are important too

Here's a good link from Hanna's site with lots of good information on all that stuff:

Every sauce maker should read up on this stuff, especially hobbyists

I check mine before using.  Same at work we check our before test wine.

I check/ calibrate before every sauce that has to be documented. Beyond that, it is frequently or as required.

I clean/calibrate mine before each use. 
Everytime.

I have a cheap Dr. Meter that arrived perfectly calibrated but sure didn't stay that way. So I calibrate every time. Ran out of calibration solution so last time calibrated to distilled vinegar assuming pH of 2.4 (made sure the sauce was way under pH 4 since that isn't a perfect calibration solution)
 
Planning on getting a better meter soon

When I want to step it up will be getting this one
