Hed-atp + ATP fluorescent bacteria detector is an upgraded product newly developed ａnd marketed by Shandong holder Technology Co., Ltd., with large screen touch screen instead of traditional buttons. Biochemical reaction method was used to detect ATP content. ATP fluorescence detector was based on the principle of firefly luminescence. ATP rapid bactericidal effect detection method was based on the principle of ATP (adenosine triphosphate) triphosphate glycoside detection. The "luciferase luciferin system" was used to detect adenosine triphosphate (ATP). ATP swabs contain reagents that can lyse cell membranes, which can release ATP from cells ａnd react with specific enzymes contained in the reagents to produce light. Then fluorescence illuminometer is used to detect the luminous value. The number of microorganisms is directly proportional to the luminous value. Because all living cells contain a constant amount of ATP, Therefore, ATP content can clearly indicate the amount of microorganisms ａnd other biological residues in the sample, which can be used to judge the health status.
