Cold Plunge Test Strips, 4-in-1 Water Quality Testing Kit, pH, Alkalinity, Hardness, Hydrogen Peroxide. Evaluate Your Cold Plunge Water Quality with A Single Strip. Smart QR Calculator to Help You

I recently tried the Caplide Cold Plunge Test Strips, and I’m impressed! They’re super easy to use and give a clear, accurate reading every time. I love how quickly they react, so I don’t have to wait to know the water quality before taking a plunge. The strips feel durable and precise, making maintaining my cold plunge routine simple and stress-free. Definitely a must-have for anyone serious about tracking their cold plunge water conditions!

Easy to use and keep track of the water quality in my cold plunge ….brrrrrr

This product is a game-changer for anyone with a cold plunge. Before using it, our water would go bad within a week, forcing us to drain and refill constantly. The online water calculator takes all the guesswork out and gives accurate results every time. For a small price, you get consistently clean, balanced water—and way less hassle. Highly recommend.

I bought these mainly for the H202 test, but it doesn't work very well. The color changes significantly over the 60 seconds window in which the instructions say to monitor the results. The other items appear to be a more consistent test.

These 4-in-1 Cold Plunge Test Strips can be reliable when they work, and reliable and convenient tool for monitoring water quality, testing pH, alkalinity, hardness, and hydrogen peroxide. They are easy to use, the problem is some of them simply do not work. The included QR code links to a calculator for interpreting results, though it references additives like baking soda and hydrogen peroxide that may not apply to all users. While not as precise as lab-based tests, the strips provide accurate enough readings for home use, including hot tubs, and pool water. It comes with a generous number of strips at an affordable price.
