AS-100 Tap Density Tester / Meter is used to measure the tapped density or packed density of powders, as well as granulated or flaked materials by standardized and repeatable procedures. It consists of LED working panel, speed controller, printer, glass cylinder and holder. AS-100 Tap Density Tester features easy operation, compact in size, light in weight, tapping height and speed controllable, tap density results printable. It meets all relevant international standards and being widely used in metal, pharma, food, chemical etc industries. 
 
Functions 
– Flexible parameter adjustment 
The AS-100 Tap Density Tester changes easily the key parameter such as tapping speed and drop height in order to meet various international standards. 
– Fast and easy operation 
The LED and mebrane control pannel brings operator a easy and fast operation. Accurate to 4 decimals. Automatically saving all the test information. 
– Reduced noise 
AS-100 is available with an optional accoustic cabinet in order to reduce the noise level, while operator can monitor the operation through the front transparent plexiglass door. 
– Easily outputing hard copy 
The integrated micro computer prints the test data including Sample No, Weight, Volume, Tap Number, Tap Density and Operator by simply pressing the button on membrane. 
– Easy to clean 
The outter surface is plastic coated, it is strong and resistant to any powders non-corrosive or corrosive. It makes for the cleaning procedure as well as a longer working life. 
 
Principle 
Definition of tapped density is an increased bulk density attained after mechanically tapping a container containing the powder sample. Tapped density is obtained by mechanically tapping a graduated measuring cylinder or vessel containing a powder sample. After observing the initial powder volume or weight, the apparatus measuring cylinder or vessel is mechanically tapped, and volume or weight readings are taken until little further volume or weight change is observed. The mechanical tapping is achieved by raising the cylinder or vessel and allowing it to drop under its own weight a specified distance by either of three methods as during tapping may be preferred to minimize any possible separation of the mass during tapping down. This parameter is very important in packing the material. During tapping of the sample, the smaller particles try to fit themselves in gaps of the larger particles and hence the total volume of the powder reduces. 
 
Applications 
Density measurement of Pharmaceuticals, Minerals, Pigment, Metal Powders, Catalysts, Coffee, Tea, Compounds and other powders suitable to be tested according to above mentioned international standards.
