Tap density testers measure how much a powder compacts under repeated taps. The test compares bulk density before tapping with tapped density after tapping. The two values give the Carr index and Hausner ratio, which indicate powder flowability. The tester offers adjustable drop height and variable tapping frequency, so settings can follow different test methods. A clear digital display shows test parameters, and a compact body saves bench space. Check drop height, tap rate and cylinder volume against the test method before buying. Results guide handling and packaging decisions. Typical samples include pharmaceutical powders, metal particles, pigments and food ingredients.
