Marimex Test Strips 4in1 - 50 pcs(11305033)

The Marimex 4in1 family pool tester provides 50 measurements, easily and quickly measuring free chlorine, pH, total alkalinity and water stability in swimming pools and hot tubs.
In three simple steps, you can find out the concentration values of the pool chemistry in just 15 seconds. We also recommend using a drop tester once every 14 days to verify the measured values.

Instructions:
1/ Immerse the strip in the water and pull it out immediately.
2/ Hold the strip horizontally for 15 seconds (do not shake excess water off the strip).
3/ Compare the colour of the pad for free chlorine, pH, total alkalinity and stabiliser (in that order) with the colour chart on the label
The correct values are measured just after 15 seconds, do not compare the values after a longer period of time.

Strip tester 50pcs. You test: free chlorine, pH, total alkalinity, cyanuric acid (Stabilizer). Ideal for those who prefer Chlorine as the main disinfectant in swimming pools or hot tubs. The 4in1 test includes testing for Cyanuric Acid, which is particularly important in outdoor hot tubs or pools as chlorine tends to be dispersed by UV light. Get 4 important results with one test! Just put the AquaChek (4in1) in your hot tub or pool for a few seconds, pull it out and you have a result instantly! The ideal way to measure is to test at least twice a week. Dip the strip into the water and pull it out immediately. Hold the strip horizontally for 15 seconds (do not shake excess water off the strip). Compare the colour of the pH, free chlorine, total alkalinity and stabiliser pad (in that order) with the colour chart on the label. The best results for the stabilizer (cyanuric acid) test are obtained when the pH is between 7.0 and 8.4 and the total alkalinity should be no more than 240 ppm. Important Note: When not in use, tighten the cap securely. Use by the date on the cap. For interpretation of the diagram on the bottle: LOW = LOW, OK = OK, HIGH = HIGH.
