5000μS/cm Conductivity Calibration Solution for Salt Meter/Saltwater Pool

The calibration packs are essentially the only way to insure an accurate water test meter stays accurate. I recalibrate once a month no matter what.

Purchased these for calibrating my ph meter and they worked just like they say. You mix each of the powders in their own container of water then you dip your ph meter in the solution and your meter will be calibrated to the value of the powder. Once you do it 3 times once in each of the solutions your ph meter should be calibrated and ready for use. You get 3 different powders and 5 packets of each one so you have more for later down the road when your meter needs calibrated again you will be set and ready to go making this a great value for the money. Seems to be pretty accurate I have tested with multiple meters and they are are very similar. Each packet is sealed separately so it's easy to store until your next use. I am happy with my purchase and will buy again when I run out of my supply. Thank you and have a blessed day!

Works well. It's accurate.

Always a good idea to calibrate a pH meter.

Two of the four bottles had leaked therefore two of the four were short the volume amounts.

Cumple lo indicado

Used it to calibrate my 5 in 1 tester which I use to test my saltwater pool.

Good.
