 DH-300K Economy Solid and Liquid Densimeter


Simple operation,Data Display, Resolution 0.001 g/cm3

Standards:According to the ASTM D792,ASTM D297,GB/T1033,GB/T2951,JIS K6268,ISO 2781,ISO 1183,GB/T11540,GB/T12206,GB/T5518 standards etc.


DH-300X is the most popular solid and liquid densimeter now; Professional measuring
accessories and high transparent unicase injection moulding tank have been equiped for solid density.which can resist wear,fall off and corrode; Stainless steel measuring frame and standard volume crystal ball have been equiped for liquid density,whose features are hommization,shorter measuring time,simple operation,stable and accurate; It is suitable for the field of quality
management,cost control,new formula researching and material studying and so on. DH-300X can be applied to measure the density of general solid material and plastic particle.Also,it is appropriate for powder and liquid.

Density resolution: 0.01 g/cm3
Maximum weigh:300g
Minimum weigh: 0.01g

Features :
Display the density of solid and liquid quickly,simple operation and stable performance.
Function of automatic zero tracking,buzzer warning,and overload warning.
Function of actual water temperature compensation,adapt to the environmental change.
Function of solution compensation.necessary if liquid other than water is used as a medium for measuring.
Adopt the unicase high-capacity measuring accessories with the transparent injection mould tank,which can resist wear,fall off,and corrosion.
Density value can be showed by one procedure for liquid densimeter.and repeatedly continuous rapid measuring can be worked.
Take samples conveniently.and 50CC would be okay.
Coordinate with the operation of thermostatic tank to measure the proportion with the required temperature.
It is very easy to clean the measuring cup,and can’t got the limitation of the size of pycnometer caliber.
Adopt the unicase dedicated wind and dust cover,which makes the combination convenient and durable.
Volatile liquid,corrosivity liquid,vicious liquid,strong acid and strong lye liquid can be measured quickly.
Interface of RS-232C is included.the printer of DE-40 will be available to connect PC with printer.

Measuring Procedure of Solid Model:
Place sample on testing board to measure weight in air,and then press ENTER button to memory.
Place sample into water to measure weight in water,and then press ENTER button to memory.
The density value is displayed.

Measuring Procedure of Liquid Model:
Place beaker samples on testing board.and take off weight of pothook.
Make standard weight hanged on pothook and submerged in liquid to be test totally.and then press ENTER button to memory.Density value can be displayed.

Standard Accessories:
Host,tank,testing board ,tweezer,thermometer,100G weight,wind and dust cover,a set of measuring floating body parts ,power transformer,DE-20A standard liquid measuring assembly
