4KW Plastic Smoke Density Tester with 6.5V Light Source, GB/T8323.2
Testing Equipment
Brief Introduction:
The main principle of smoke density measurement is that in a
particular space, the cable or material produces smoke under
specific combustion or radiation conditions, and the light beam
penetrating through the smoke will produce attenuation. Measuring
the light transmittance and calculation will get the optical
density and smoke density.
The instrument is designed and developed according to ISO5659
related standards.
With the use of Conical radiation furnace, the heat flux in the
chamber can be as high as 50 kW per , and the sample can be
positioned horizontally to test the mass loss rate of the sample.
This also complies with the latest IMO test terms. Measure the
amount of smoke generated when the sample is vertically exposed to
a radioactive heat source at 25 kW / m2 when there is or there is
no forward flame in confined space.
Using the standard ISO 5659 conical radiant heating furnace, the
user can adjust the heating conditions from 10 kW into 50 kW or
70kW

Feature:
1. The tester consists of a chamber, a sample box, a radiant cone,
an igniter, a light transmission and measuring device and other
related control devices.
2. Ergonomic design and control design; chamber with a fully open
door ; door lock designed to facilitate one-time closure of the
door; optimize the operation process.
3. The test chamber door can be fully opened to facilitate loading
and unloading samples and cleaning the box;
4. Front door, hinge mounted, with window and non-transparent light
shading board which can block the window, to prevent light from
entering the sealed chamber.
5. The controller is located on the side of the chamber for easy
operation. When the door is closed, it does not affect the
controller to be viewed.
6. Safe flameout board, easy to replace, more secure operation.
7. A gas measuring port is available for testing gas toxicity.
8. The coating of the test chamber is easy to clean and resistant
to chemical corrosion.
Combustion Apparatus:
1. Heating cone: power 2600W, input temperature range of 0 ~ 1000℃,
stable within ± 2℃ within 50 mins, can provide 10KW / m²-50KW / m²
of radiation exposure.
2. The use of mass flow controllers and differential pressure
sensors enhances the accuracy of the manometer and enables
automatic leak testing.
3. The ignitor is equipped with automatic ignition device; flame
length 30mm ± 5mm; in accordance with the standard provisions of
blue flame with yellow on the top.
