DENSIMETER

Electronic Densimeter for Wood 

เครื่องวัดความหนาแน่นของไม้ 

MODEL : MH-300W / 600W

Suitable For : Wood, Construction Field, New Materials Research

Principle : According to ASTM、GB/T、JIS、ISO standard, adopt the buoyancy method of Archimedean principle, can directly measure the density accurately and fast.

Technical data :

- Density is an important parameter for wood when measuring its physical charater and mechanical character. As we know, Wood is a biological tissue made of cells, tracheides, and of walls composed of lignin. The tracheides are like pipes, transporting the sap along the stem till they are filled wirh water.

- Wood density varies within the plant, during the life of the plant, and between individuals of the same species. Also the branches and the outer part of the trunk tend to have a lighter wood than that of the pith.

- According to the definition of wood density, foreters measure the weight of a given volume of wood that has been 'air-dried'. Depending on the standards of different countries, conventions differ about air drying the fraction of water remaining in the wood sample may be 12%, or 15%. In the present study, wood density is technically defined as the ratio of the oven-dry mass of a wood sample divided by the mass of water displaced by its green volume (wood specific gravity or WSG). This can be calculated from measurements of oven-dry
