Ph meter

Well lads,

I bought a ph meter of amazon no brand name juz a 10e one. When i first got it and calibrated it it worked fine. Now after a few months after taking a reading and rinsing it in tap water the reading never returns back to zero, is this normal or is it fucked?

I don’t think you should rinse with tap water, maybe de-ionised or RO.

It won’t go back to zero anyway because it’s constantly reading PH levels while it’s on. Zero would be a super acidic solution. They usually hover around 6-7 when you turn it on until you submerge it in a solution, I have 3 different meters and they all do this.

PH zero means extremely acidic, not no reading lol

You need to use a Storage liquid and keep the tip moist
I refresh mine once a week and yes yours is probably a lost cause

Sound for the replys lad, ill stay going with it for now better than nothing and ill upgrade later on

Just buy some pool test litmus strips for about $3
Better than relying on a false reading

I don’t use any storage liquids, I calibrate them every 2-3 months... Never far out... maybe 0.1 - 0.3. You’re probably fine pal i wouldn't worry too much if I were you.

Except thats not the correct way and you will find the more exspensive ones replacable and built to store in the Kcl storage fluid as standard.

Lol while I don’t doubt that is the correct way, I’ve bought cheap ones, rinse them in de-ionised, and calibrate them periodically. Haven’t had any issues. Though I do have litmus for backup!

I’d rather buy 7 shitty ones at £10 each over a year than one good one for £70, makes me feel like I’m getting more for my money

Never wrong.

I wanna find some temp and RH meter like this,any guys have idea where to get some ? lol
