For fast, professional hygiene/cleanliness monitoring, particularly in the food industry, healthcare and pharma industry. How it works : device measures the content of ATP, a molecule present in all living cells. The more ATP present, the more biological residues there are and so the greater the contamination. Sampling is carried out using a special swab (Quickswab) that is treated with a reagent that reacts when in contact with ATP. Lightweight measuring device, fast measuring time Measurement value memory for up to 256 users and 10,000 recordings, incl. time and date stamp Data transfer and analysis using Windows-compatible software, please download free of charge Automatic cleanliness test before every use; self-test prevents incorrect measurement results from contamination, primarily in the measurement chamber Automatic self-calibration (checking + adjustment) for reliable, accurate measuring results ATP measuring device PCE-ATP 1 basic Delivery incl.
