Bluelab Calibration Solution pH 4.0, 7.0 and 2.77 EC Conductivity Solution, 500 ml Each

Exactly what I expected

If your using a ph meter or dissolved solids meter this is a must have. Not cheap but accurate. If you want your grow to turn out right you need accurate info on your water ph and fertilizer strength. Don’t think you can compromise here. Not cheap but reliable.

Exactly as described sealed bottles and Very fast shipping! Couldn't be more satisfied with purchase.

Got these super quick! Haven’t used them yet but they look as expected.

Works great when calibrating.

Very good

Do believe the shipping... it really does take that long. Packaged up soon after order but took week to actually get to carrier and shipped. Not a big deal. Why lie though?

I bought this product and never received ppm solution to cal. It I got the ph cal. Not the conductivity 1 tho messaged and never responded back what a joke

Showed up on time and exactly what I ordered

All good

This is a good deal and I will purchase again

Everything sealed and new, just as described. Make sure to read labels and instructions printed on each bottle. Would recommend to anyone (using with non bluelab equipment and its working great)

Un peu plus dispendieux mais livré à la porte !👌
