Electronic Densimeter for Wood MH-300W

Suitable for: Wood, Construction Field, New Materials ResearchPrinciple: 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 character 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 with 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, foresters 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 weight combined with measurement of green volume.Specification Model MH–300WMeasurable range 0.005g~300gAverage weight 0.001gResolution 0.001g/cm3Testing time About 10 secondsSetting Compensation of water/temperature and other medium of solutionFunctions Can directly show the basic density, apparent density, wet density, apparent porosity and water absorbing capacityStandard interface RS-232Optional equipments:A:Automatic vacuum siphon machine MHV-2 B:Infrared moisture meter aim: vacuum Saturation water treatment aim: to dry the moisture at100~105℃
