HYL-103 natural accumulation loose density meter is designed and produced according to the national standard GB/T16913.3-1997. This device is suitable for the determination of dust accumulation density.

For the collection of samples, please refer to GB/T16913.3-1997 Experimental Methods of Dust Physics Part 1: Relevant regulations in the collection of sample dust.

1. Principle

Dust falls freely from the funnel mouth at a certain height to fill the measuring cup; Determine the mass of dust per unit volume in the measuring cup in the loose state, that is, the dust accumulation density. 2. Instrument structure

2.1 Funnel (outlet diameter 12.7mm)

The funnel is made of stainless steel, in which the funnel taper is 60+/-0.5 2.2.

Stainless steel material, used to prevent dust from falling when it is loaded into the funnel. 2.3 Balance (provided by users)

Maximum weighing 100g; Accuracy 0.02g2.4 measuring cup

This device is equipped with a stainless steel measuring cup with a volume of 100ml, and the inner diameter of the measuring cup is →39mm2.5 scraper.

Stainless steel material, used to remove excess dust when it is loaded into the funnel.
