Spa and Hot Tub Test Strips - 5 Way Chemical Testing Strip Kit Tester for Chlorine & Bromine Spas & Tubs - Calibrated for Warm Water to Maximize Accuracy - FC TC/TB Alkalinity pH & Hardness - 50 ct

Good item. Hard to read

Easy to test hot tub water very quickly. Love the total hardness test which was a low priority with other strips. Easy to read and correct with appropriate items. Love them.

I like the accuracy of the strips and I use them for my hot tub.

I bought these for my spa. I use chlorine but it can also measure bromine. Plenty of strips to last awhile (since I don’t test my water every day). The water has been crystal clean since I started using these. Will purchase again.

Great !

Great strips, thanks.

Bought this product for are hot tub. It's really easy to use because you just dip it in the water and read the colors on the strip and on the bottle. The only complaint I have is that the ph part isn't giving me an accurate reading. I've used one whole bottle and every time it is a watery puddle on the ph and not any color at all. When I use a different tester that's not those strip my ph is fine.

As new hot tub owners we are vigilant about monitoring the water quality. These test strips are quick & easy to use.

I’ve tried a number of different testers over the years but this one is highly effective and is one I shall reorder and reorder…!

Istruzioni solo in inglese. Non si capisce come si deve confrontare con la tabella che ha una striscia in più. Risultato, per me, incomprensibile.

Me ha costado equilibrar el agua del jacuzzi, pero finalmente lo he conseguido gracias a este analizador de agua. Los valores que da son precisos, claros y fáciles de entender.
