It is doing pretty well. Calibration required. Does a pretty good job and is very convenient

Useful, accurate and easy to use
I use this to do spot water quality tests on the water coming from the private well that feeds my home. For the most part, it's easy to use and is as accurate as any tests I've tried. TDS, Salinity, ph and conductivity are easily determined from a single test sample in under five minutes. Of course, it would be ideal is the unit could also test for additional contaminants (iron, nitrates, chlorine, etc), but for what it offers, this is a great probe that gives you a quick understanding of whether you've had any changes to your water quality.Definitely a good way to get started with water quality testing.

Good little meter.
Easy to calibrate with known lab grade pH cal standards. 4,7,10. Compared this meter to lab a grade Hach ph meter and the readings were spot on after calibration.Comes with a sponge in the cap and a little sample cup that allows the meter to sit in the solution being measured.

Disappointed
Very disappointed.I've now had 2 of these units quit calibration.1 will not calibrate pH the other will not calibrate ec.They work well for a couple months and then just won't calibrate any longer, change the probe calibrates then stops reading correctly tried new solutions tried soaking the probe tried resetting the meter changed the batteries and still not working.It's really ashame because I like these meters they are easy to use but even with proper care they just don't last very long

Good and handy
This is a decent meter. Overall, it seems to be well constructed for the price. I like being able to do conductivity and pH on the same meter, which this meter does fairly cheap. I wish they sent buffer solutions in the box, although I have heard of some cheap ways to make your own. I like the temperature readout, too.I think with more buttons it would be easier to scan through the different modes and menus, like what if there were dedicated keys for each unit?

Inaccurate readings
Not very accurate, I tried calibrating it and still has inaccurate readings (+/- 2.5). I compared it with Myron L Ultrameter II
