A swab sample will be tamed from items such as seat belts, car seats, steering wheel and dash board before and after the cleaning service to compare the microorganisms and bacteria level.
We adopt Hygiena SystemSURE Plus™ Luminometer to perform the test. The device gives a numeric measurement of organic material (ATP) on a surface, measured in relative light units (RLU). The more ATP presents on a surface, the higher the RLU measurement.
