Product Description
Repose Angle Measurement Instrument
The angle of repose is the angle (relative to the horizontal base) of the conical pile produced when a granular material is poured on to a horizontal surface. It is related to the density, surface area and coefficient of friction of the material concerned.
DF-1-05 repose angle tester is designed and produced based on ISO 4324:1997.

FAQs of Repose Angle Measurement Instrument:
Q: How is the Repose Angle Measurement Instrument operated?
A: This instrument utilizes a manual control system, operated entirely by hand. Users place a powder or granule sample (typically 50100 g) onto the flat, removable platform and use the integrated manual cone lifter to form a powder cone. The repose angle can then be read directly from the high-contrast graduated scale.
Q: What materials is the instrument constructed from, and how does this benefit the user?
A: The unit is made from mild steel with a powder-coated, anti-corrosive finish, delivering durability and resistance to corrosion. This ensures a long lifespan for the instrument, even in laboratory environments with varying humidity and temperature.
Q: When should the flat, removable platform be cleaned, and how is this done?
A: The platform should be cleaned after each test or when changing between different powder samples to prevent cross-contamination. Simply remove the platform and wipe it with a lint-free cloth; mild cleaning agents can be used if necessary.
Q: Where can the instrument be installed or used?
A: Owing to its compact benchtop design, the instrument can be set up in any laboratory or research facility equipped with a standard 230 V AC supply. It is suitable for use in environments with temperatures from 10C to 50C and relative humidity of 5% to 85% (non-condensing).
Q: What key processes are involved during repose angle measurement?
A: The main steps include loading a pre-weighed powder/granule sample onto the test platform, manually forming a cone using the lifter, leveling the device with the screws, and then reading the angle of repose from the analog graduated scale for immediate results.
Q: What are the advantages of using a manual repose angle measurement instrument?
A: The manual interface removes reliance on electronic components, reducing maintenance needs and simplifying operation. The analog system provides instant, accurate measurements, while the removable parts facilitate easy cleaning and prevent material contamination.
