Why pool professional need the eXact® Micro 10
The FAS-DPD drop test has been a favorite test for many pool service personnel for the last several years for testing pools or spas for Free Chlorine, Total Chlorine, and Bromine (total). This test was adopted by the professionals because you could detect 10 PPM and higher, the test is accepted by Health Departments, and the test does not require for you to distinguish between shades of pink. These benefits drove an almost universal adoption of the FAS-DPD test.
But the professionals had plenty to complain about the short comings of their FAS-DPD drop test kits:
The titration for 10 PPM chlorine required a lot of drops to be counted ( 50 to be exact for 10 PPM) and stirred
Math was required to determine the chlorine (or bromine) concentration.
Sensitivity was no better then 0.2 or 0.5 PPM for chlorine and for bromine it dropped to 0.5 or 1.25 PPM.
The drop test was especially deficient since the lowest level of Combined Chlorine you can detect was 0.2 PPM and this was the Health Department's official regulation at which point pools should be shut down for shocking. (maybe that is why public pools in general are kept at a chlorine level of 4 PPM and higher-to keep shock issues at a minimum)
FAS liquid reagents often were unreliable due to short shelf life and sensitivity to summer heat and the DPD powder or liquid reagents were also problematic.
Additions of powder DPD are cumbersome with the small cup.
