3M KCL Storage Soaking Solution (8 oz.) for pH and ORP Electrodes

I use this to lower pH of wort. Works great

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 well. Does what it is supposed to do.

seems to work ok but crystallized on the top edge of the cap

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.

Excelente producto, tal y como en la descripción.

Exactly what I needed!! Needed this for storing my Apera Ph60! Does exactly what it's suppose to! Easy to use!! Lasts a long time! It arrived safely with no leaks!!

A must have for proper instrument storage. Shipped without leaks. No questions in quality.
