EC500 Waterproof ExStik II pH/Conductivity Meter | 5 parameters: conductivity, TDS, salinity, pH, temp; 9 units, analog bargraph, stores 25 readings

Great piece of kit for my work. Just remember to follow the calibration instructions 👍

Item as described!!!

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

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.

¡Funciona perfecto! Lo volvería a comprar.

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.

Works perfect, will see future review after I give it a well used. UPDATE 2016: This is great, after some time using it was perfect until someone else ustis and break it, I think this is very good quality product so no blame extech for this. I will get a new one soon to replace the other.

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