TDS meter recommendation?

[faithie999]

does anyone have a recommendation for a decent TDS meter? I don't want to buy a Pro-level one, but I want to keep track of my RO membrane.

thanks

My RO system came with inline ones for source and output, but before I had that I used this one to check the stuff coming out of the bulk water machines:

I checked on the one I bought from Amazon and it's not currently available. IIRC, I paid about $15 for it and it's been fine. It doesn't have be that accurate.

A tds meter is a somewhat crude instrument that you shouldn’t assume is precise. But they are a very good ‘relative’ measure. They show the change between subsequent measurements pretty well.
I’ve had good luck with the units from HM Digital. Their handheld units are fairly inexpensive, probably under $30.

I have an HM Digital tds meter I bought many years ago for $8 delivered by amazon.
From all appearances it works well...

Cheers!

We have the handheld TDS3 on sale, and the DM1 would also be worth taking a look at.

+1 on the DM1.

I have been using a DM1 I got from Bulk Reef Supply 9 years ago (technically nine years in February) and it has never let me down.
