Apera Instruments3M KCL Storage Soaking Solution (8 oz.) for pH and ORP ElectrodesCarbonfree Certified

I have a smart pH sensor for my pool that needs to be stored in 3 M KCl solution during the winter months when the pool is closed. It only needs a tiny amount of fluid, so this container is a little bit of overkill, but compared to some other products this one is pretty inexpensive, making it the best choice. It's the proper concentration that my sensor manufacturer specifies, and the bottle is easy to handle and pour. It arrived without any leakage and is just what I needed!

Works great. Pen stays calibrated between checks

Excellent product, does what it's supposed to and keeps my apera ph20 ready to go for daily use. My only gripe would be that a storage solution should also come with the ph pens. Other than that, this product does what it's supposed to and apera knows what they are doing! With this solution I've only had to calibrate my ph20 2 times in the 5 months I've had it.

Good price. We have another pH meter require 4M KCL for conditioning, that’s 3 times the price of this. Definitely worth getting the pH meter from this reliable company

Pretty standard but good price and no leaks so I’m happy!

fast bottle came seal in its container plus a zip lock bag for added protection from leaks package well in box will buy aagain

Great quality for the price.

Used to do bunch of testing whether it was hawk or whatever even if I made it three molar it's three molar grate for preserving your probe you gotta have it.Oh end it burns like I'll get out when it gets in your cuts just like the real deal from the real deal companies if you're wanting some 3M KCl go ahead and just hop on this train
