ATP Measuring Device PCE-ATP 1-KIT / quick hygiene measurement / simplest sampling / USB and Bluetooth interface / self-calibration upon startup. The Lumitester PCE-ATP 1-KIT is used to quickly and easily check the cleanliness of surfaces. The Lumitester displays a measurement result on the large LC display after just 10 seconds. The internal memory of the luminometer can store up to 10,000 measurement records with date and time. The Lumitester PCE-ATP 1 allows for a quick detection of food or microbiological residues on all product-contact surfaces using the associated PCE-ATP SwapPen, serving as an effectiveness check for cleaning and disinfection measures. The quantitative determination of intra- and extracellular adenosine triphosphate (ATP) is performed in the portable Lumitester PCE-ATP 1. The measurement data from the Lumitester can be saved and further processed after the measurement. The Lumitester is used in hygiene control in pharmaceuticals, medicine, gastronomy, wholesale, etc. Measurements with the Lumitester are conducted using the specially available ATP test tubes. The surface is sampled with the swab contained in the tube. The swab is then pressed all the way down into the tube, allowing it to come into contact with the reaction liquid and the actual reagent. By gently shaking, the reaction liquid collects in the reaction chamber of the tube. The entire test tube is then inserted into the measurement chamber of the Lumitester PCE-ATP 1. The measurement is then started. After 10 seconds, the measurement result in RLU (Relative Light Units) is displayed on the Lumitester's screen. The Lumitester PCE-ATP 1 can be used in various business sectors, enabling seamless control and documentation in the food industry.
