Got a new pH meter!

[Slugtrail]

So I was lucky enough to get a brand new pH meter and I was wondering if I should calibrate it before I use it or is it ready to go out of the box?

I would calibrate it no mater what, anything can happen during shipping or storage of the meter.

Check out this epic post wrt pH meter calibration and stability testing. Totally worth the read.
fwiw, I use a Hach Pocket Pro+ and go through the calibration procedure before every brew day...

Cheers!

I'm probably getting the Pocket Pro+ too, trippr, based on what I've read from AJ and others here, yourself included now (didn't know that's what you use). I always used an Extech 110, though, and though I had to go through a few (QC is abysmal - the company simply sent me a new one, twice, no discussion at all...they're used to it), when I did finally get one that wasn't a dud, it worked well for me in cheesemaking. Have you come across the Extech, by any chance?

To add my $0.02, Slugtrail, yep, absolutely, I'd calibrate. And like trippr says, do it every brew day. I used to 2-point calibrate 2-3 times during a long cheesemaking day, to be honest. But that's probably freakish overkill.

No Extech experience - with any of their meters. Have been eyeing their O2 meter, though.
wrt pH meters, I've used a borrowed MW102 (unwieldy pita probe), then a Hanna HI98128 (fatally flawed calibration firmware) and finally the Hach.
Of the three I'd go with the Hach every time...

Cheers!

Calibrate at each usage.
