ATP is a molecule that stores and transfers energy in almost every living organism on Earth — even you. Harnessing this science, our AccuPoint Advanced NG instrument measures the amount of ATP present using relative light units (RLUs). The RLU thresholds are based on established criteria to reflect effective cleaning practices and can be raised or lowered according to your needs. When verifying the effectiveness of your sanitation, the less ATP, the better. Testing your environment with our system accurately detects any low levels of ATP residue, even when a surface appears visibly clean, for confidence in your sanitation verification.
