Optional measurement
ATP cleanliness testing
A simple number that shows how clean a surface is right now.
How it works
A swab is rubbed across a defined area of a surface and read by a handheld meter, which reports a relative light unit (RLU) value. A higher value suggests more organic residue.
We record the surface, the reading and the time, and include it in your report.
How to read it
ATP values are relative. They are most useful as a before-and-after comparison on the same surface, not as a pass or fail.
