Description du produit :
Qualtech Produits Industrie Densimètre à tapotement is a precision density measurement equipment to determine the Bulk Density et le Tap Density of powders at the touch of a button. The Tap Density est le Bulk Density with a much higher accuracy which is achieved through tapping a measurement glass cylinder which contains a powder sample.
Pour mesurer le Tap Density of powder samples, the sample is filled into a specified Glass Cylinder of the Densimètre à tapotement with an engraved precision graduation presenting the volume or mass of the powder sample. The Glass Cylinder is automatically tapped by the Tap Density Meter, raised by motor-driven precision mechanics to a specified height and then dropped under its own weight from the specified height. The Tap Height is continuously adjustable. Now the Tap Density can be read from the graduated Glass Cylinder.
Ce professionnel Densimètre à tapotement offers the newest microchip technology combined with a large Digital Display for comfortable reading under different light conditions, Digital Display presenting Tap Frequency & Test Parameters & Test Results, comfortable Softtouch Buttons, user-friendly Application, user-friendly Programming, user-friendly Sample Handling, a continuously adjustable Tap Height, an integrated Thermo-Printer to instantly print measurement data, high accuracy and high precision, an ergonomic design, a reliable performance longevity and much more.
Cette précision Densimètre à tapotement is available with one, two and three sample measurement Glass Cylinders to conveniently measure up to three sample simultaneously at the touch of a button.
This professional Tap Density Meter is designed and engineered in accordance with international test standards including:
- ASTM B527 (Standard Test Method for Tap Density of Metal Powders and Compounds)
- ASTM D4164 (Standard Test Method for Mechanically Tapped Packing Density of Formed Catalyst and Catalyst Carriers)

Automatic Tap Density Meter - Caractéristiques :
Ce professionnel Automatic Tap Density Meter détermine le tap density of powders by subjecting a known mass of material to a controlled sequence of vertical taps. This process compacts the powder bed in a highly repeatable manner, reducing inter‑particle voids and allowing engineers to quantify how a powder behaves under mechanical consolidation. The instrument automates the tapping motion, drop height, and cycle count according to standards such as ASTM B527, ISO 3953, and USP <616>, ensuring consistent energy input and eliminating operator variability.
During the test, the powder is placed in a standardized graduated cylinder or density cup, and the instrument performs a defined number of taps—typically 1250 or 3000—while continuously measuring the powder volume. The resulting tap density is calculated as mass divided by the final compacted volume. This value correlates strongly with particle morphology, surface texture, flowability, and packing behavior. Powders with spherical, smooth particles generally achieve higher tap densities, while irregular or porous powders exhibit lower compaction efficiency.
For experts, Tap Density is a critical parameter in powder metallurgy, additive manufacturing, pharmaceutical granulation, and chemical processing. It influences die filling, dosing uniformity, flow stability, and bulk handling performance. This Automatic Tap Density Meter provides superior reproducibility compared to manual tapping devices, enabling reliable batch‑to‑batch comparison, material qualification, and process optimization. The automated method also supports advanced analytics, such as monitoring densification curves to study powder compressibility and consolidation kinetics.
