ATP (Adenosine Triphosphate), is the energy molecule found in all living things, making it a perfect indicator when trying to determine if a surface is clean or not. Typically, readings below 100 is considered “Clean” and readings above 500 is considered “Very Dirty”.
The ATP reading before application was 234. We then applied TAG Shield and left it to cure for 24 hours. The ATP reading after 24 hours was 10 which falls under the “Ultra Clean” or sterile level.
Watch the video below which shows how a ATP test is carried out.
