ITS Europe Pool Check 5in1 Bottle of 50, Pool, Spa, Hot Tub Test Strips (Total Hardness, Free Chlorine, Total Chlorine, Total Alkalinity, pH).

I purchased these to use for testing the levels of my hot tub. They are very efficient and you get a good quantity for your money. Only suggestion I would make is to make them just a tad longer for holding room. I am finding that I am putting my fingers on the sample patches when removing them from their container. Slight concern that this would tamper with the results.

I have had many different kinds of these test strips and, to be honest, these are not the best. They are okay the colours seem more runny and less definite than they have on some of the other brands I have purchased.

These work ok but the colours wash out to easily as reagents not strong enough.

I tried these for the Calcium Hardness test. They work but are not brilliant quality. Some of the patches show areas of different colours in use! The pH test is a bit vague compared to others. The packs have a sell-by date, so don't buy too many at once.

Not bad strips and do pretty much what the box says. Like the total harness and alkalinity.

It does what you expect

Bit disappointed ordered 2 x tube and the expiry date is April 2107....poor show and little underhand..!

Very good way to measure all factors you need. 50 strips in the tub, so very good value too. Colours easy to read and understand, would recommend to beginner like me.
