This morning we received an inquiry from 'Colina' who asked, " Hi. I have an impatient know it all boss and while I was on vacation last week he ordered several bottles of your 481026 SenSafe Free Chlorine Water Check which we can use for most of our testing, but not ALL of our testing because some of our water samples have higher than 6ppm free chlorine in them. He SHOULD have ordered the 480023 Free Chlorine Product like have in the past. Is there a way we can still make the stuff he ordered work or do we have to return it and buy the right bottles like he should have in the first place? Thanks in advance for your help!"
And we thank YOU, Colina, and your boss for all your business! Regarding the two products, both detect concentrations of free chlorine in water samples and as you know, the SenSafe 481026 product detects up to 6ppm and the WaterWorks 480023 product detects up to 25ppm.
Dilution method
To use the strips you have, you will need to use a dilution method. Below you will find two examples of how to properly dilute a sample and back calculate the free chlorine concentration.
NOTE: Make sure you use distilled or other water known to possess a zero chlorine concentration for dilutions.
- 1 part distilled water + 1 part water sample ... Perform a test using a test strip ... If you get a reading on the strip that matches one in the strip's color chart range, multiply that reading by (2) two to get the actual concentration of chlorine in your water sample.
- 2 parts distilled water + 1 part water sample ... Perform a test using a test strip ... If you get a reading on the strip that matches one in the strip's color chart range, multiply that reading by (3) three to get the actual concentration of chlorine in your water sample.
As a general rule we always suggest having the proper tool for any testing job. Therefore we carry WaterWorks & SenSafe brands of water test strips for chlorine testing with varying detection ranges:
 SenSafe Free Chlorine Water Check Detects 0 - 6 ppm |
 SenSafe Total Chlorine Test Strips Detect 0 - 10ppm |
 WaterWorks 2 Free & Total Chlorine Test Strips |
