DSHD-255G Boiling Range Tester is designed according the National
Standard of People’s Republic of China GB/T7534-2004 “Test Methods
for Boiling Range of Volatile Organic Liquids for Industrial Use”.
DSHD-255G Boiling Range Tester is widely used to determine boiling
range of volatile organic liquids for industrial use and organic
solvents for material.
DSHD-255G Boiling Range Tester can also be used to determine
distillation characteristics of gasoline, aviation gasoline, jet
fuels and similar petroleum products when you operating with proper
B: Main technical features:
(1) The electric furnace is mainly composed of SiC furnace base,
1000W, 220V electric heating wire, and SiC board, which can
withstand high temperature. The height of the electric furnace can
be adjusted using the height adjustment knob on the electric
furnace case. Its heating power can be controlled by voltage
adjustment knob on the control panel.
(2) The electric furnace moving boards are made of SiC boards. The
diameters of hole on them are φ38 mm, and φ50 mm respectively.
(3) The water bath is composed of overflow tube, temperature
adjustment tube, and water bath. The bath size is 244 mm×167 mm×176
(4) The electric furnace case is made of cold rolled steel sheet.
There is an observation window in the front of upper section. The
electric furnace and distillation flask are installed on it. The
electric circuit controlling part is installed on the lower section
of the case.
(5) The distillation flask is made of harden glass. The outer
diameter of ball type section of the flask is φ65 mm. The inner
diameter of the flask neck is φ16.9 mm. The angle between the
branch tube and flask neck is 75±3 °.
(6) The condensation tube is made of copper tube of φ14. Its outlet
likes arc. It is about 560 mm when it is straighten.
(7) The graduated flask is 100 ml; its scale division is 1 ml
(8) The thermometer is glass mercury type
