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

Works as expected.

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.

I wish I would've done some research on PH pens before I went threw 3 of them. But then Apera helped me learn whenever they offered this solution with a bundle whenever I got my Apera PH20 great pen too BTW

I use this to lower pH of wort. Works great

Excelente producto, tal y como en la descripción.

Quick delivery, excellent packaging to prevent leakage, and good price for this essential item to maintain my Ph meter.

Helped refresh a PH probe by bathing in a warmed up solution for an hour, probe now much more stable
