pH Meter: Balancing cost and quality
« on: January 17, 2016, 02:55:24 PM »
I'm looking to get a pH meter. I understand everyone has their preference and am looking for objective opinions on sub $30-$40 pen style meters.

I'm not looking for the supreme accuracy and  precision of the more expensive units but would like something that can confirm my Bru'n water predictions with better accuracy than strips.

Any suggestions would be welcome.

Thermoworks has one. Never used it, but I like my thermopen.

Can't comment on the 30-40 dollar ones, but I own a MW101 and could't be happier.  In addition I feel really cool when I use it.

I wouldn't waste money on a meter that has an accuracy worse than +/- 0.05.  Also remember that the probe doesn't last more than a couple of years.  I got the MW102 because of the .02 accuracy and because you can replace the probe for $30 when it becomes necessary.

Plus, storage and calibration solution is going to cost another $30 or so.  It's not worth spending that money if the meter isn't good.

Understood. I'm looking for something more accurate than strips but not as accurate as the MW units I see around. MW has a pen type meter for around $50 with .05 accuracy that looks promising. Replacement probe is $30.

They also sell a cheaper pen meter with 0.1 accuracy that may be what I'm looking for.

Don't be penny-wise and pound foolish. From my review of the market, I don't think you will find something that provides good response and service for less than $50. Even at that cost, it will still be iffy. Decent equipment starts at about $70.

I am a big advocate of choosing a meter that has a non-proprietary, replaceable probe.

The question I'd ask is if, for the price of a cheap meter and solutions and replacement probes in the future, it's worth only knowing that your pH is between 5.3 and 5.5.

All great points. I'm leaning toward the MW P56 with the .05 accuracy.

The pH56 unfortunately has a terrible reputation. Think twice.

You can get an MW101 for $70 on Ebay with free shipping.
It's too close to home
And it's too near the bone

I have MW-101 now, and am happy with it. Buy once, cry once.

As Narvin said, you need the calibration solutions, storage solutions, and you can buy the electrode cleaning solutions too. You will have $40 or so invested if you get all 4. That is just to maintain the probe and make sure you are accurate. Why not spend the incremental $ to get a good meter over the basic meter.
