LaMotte Insta-Test 4 Plus, Free Chlorine, Bromine, Alkalinity, pH, Total Hardness Testing

These are great test strips. They are more expensive, but worth the extra. These are far superior to some of the cheap brands which I had found to be very unreliable (completely wrong!). I had previously brought some cheap test strips on eBay, and ended up using a lot of chemicals unnecessarily, trying to correct a problem which didn't exist. LaMotte are a proper company who specialise in water test equipment, so I trust these and have found them to be very reliable so far. The moral of the story is don't try to save a few pounds by using cheap test strips, as it could cost you a lot more in wasted chemicals, and time spent trying to put things right again. Just buy some good quality test strips (like these), and get it right first time, so you can enjoy your pool!

Sacas una tira, la metes en agua, la sacas del agua y comparas el color con el dibujo. Se ve perfectamente el nivel de cloro y demás datos.

Work s good. Very easy and accurate

After 20+yrs with spas I have determined Lamotte strips are the most accurate with a vibrant color display for all chemicals. The Lamotte 4 is for Chlorine based chems while the LaMotte 5 does both Bromine and Chlorine. Others I had were junk and these last for years.
