TDS meters.

Ok so I have 3 of the popular TDS3 ppm testers.

I splashed out on some calibration fluid and all 3 failed.

The newest is about 60 out the oldest about 80 both above what they should read.

The other one is about 60 below what it should read.

Only the oldest has an adjustment screw but it doesn't seem to work very well.

So how do we know what our pure readings really are.

In all fairness I got talking to another wfp user about 6 weeks ago and we tested my water using his meter and mine and they both agreed on 2.

i have 2 TDS meters and they both read the same when testing my water......one has a temperature option which is handy.

ive never used calibration fluid...i couldnt be bothered TBH!

id just buy a new one if i thought it was dodgy....

Are they genuine or eBay fakes?
