Pool Check 4+ Test Strips
Part No. 481341
Tests for:
- Free Chlorine
- Total Chlorine/Total Bromine
- pH
- Total Alkalinity
This 4-in-One pool & spa check is a complete test kit, which tests for 4 key parameters: free chlorine, total chlorine, pH, and total alkalinity
- More colour blocks result in better accuracy and precision
- The pH indicator (BTB) provides easy colour matching for improved accuracy
- The TMB indicator for Free Chlorine is accurate and uses a same patented indicator as EPA approved test strips
- The 5 seconds dip time with motion allows lower detection levels and even colour development
These test strips have a unique safety feature, which is called 'bleach-out' warning: if there is too much chlorine in the water they will go black.
Other test systems may not show when chlorine levels are too high. Quite the opposite, when more chlorine is in the water than a test can measure for, the indication maybe 'zero' which can result in dangerously high levels of chlorine in the water. The 'bleach-out' warning stops this from happening and ensures high safety for pools and spas, and hence these test strips are preferred by industry professionals.
It is ideally suited for pool & spa owners who want to make sure that their pools & spas are safe, properly maintained and looked after.
How to use: Simply dip one test strip into your pool or spa for 5 seconds with a gentle back-and-forth motion. Remove the strip and shake once, briskly to remove excess water. Wait 15 seconds for colors to develop. Compare test pads with color chart on the bottle within the next 30 seconds for best results.
