Machine Model: JCY-3 TypeTobacco Density Tester   One.Smoking Density TesterApplication Scope:
Touchscreen dual-control smoke density tester for building materials, developed in accordance with the technical specifications of National Standard GB/T8627-2007 "Test Method for Smoke Density of Combustion or Decomposition of Building Materials," is suitable for determining the static smoke production from the combustion of building materials, their products, and other materials.

II.Smoking Density TesterFeature Highlights
Dual control method, operations can be controlled on the touch screen or via computer, with the flexibility to switch control modes as desired!
2. One unit can be operated by several computers simultaneously, allowing multiple computers to be online at the same time, and enabling local area network sharing!
3. The main and auxiliary burners can automatically rotate and are accurately positioned.
4. Self-developed control programs, capable of meeting various operations, records, real-time curves, and result calculations during the tests.

III.Tobacco Density TesterRelevant technical specifications
For the smoke density (MSD) and smoke density ratio (SDR) of the sample: Continuously measurable from 0-99%, automatically calculated.
2. Standard light filter correction errors should not exceed 3%; each unit is equipped with three standard light filters, and the data corrected for the light source is representative.
3. Bunsen burner working pressure: (210±5) KPa
4. Apply flame to the sample with a Bunsen burner for 4 minutes.
5. Bunsen Burner: 260mm in length, nozzle diameter of 0.13mm, at a 45° angle to the ashtray.
6. Photoelectric System: Light source is a bulb, power rating 15W, operating voltage 6V.
7. Exhaust System: This machine is equipped with a powerful exhaust fan, which can expel waste gases outdoors after testing.
8. Smoke Density Measurement Range: 0~99%
9. Smoke density measurement accuracy: ±3%
10. Receiver: Silicon photovoltaic, with 0% light transmission meaning no light passes through, and 99% light transmission indicating light passes unobstructed.
11. Main Burner Operating Pressure: 276 KPa (adjustable)
12. Automatic timing, automatic ignition, automatic smoke exhaust; luminous flux can be segmented linearly corrected for test data
More accurate.

4. Gas Pressure: 0-0.3 MPa (adjustable)
5. Environmental and Test Requirements: Avoid direct strong light exposure or reflection onto the instrument during operation; after 90 minutes of testing, shut off the gas source to cool down the instrument for 15 minutes.
6. Environmental Airflow: No forced air flow during operation.
7. Instruments should be tested within a fume hood.

V.Tobacco Density TesterStructure:
Divided into two major parts: cigarette boxes and control.
Tobacco Box Section: The left and right side panels of the tobacco box feature a power switch, a safety sign switch (backlight switch), a gas regulating device, as well as a switch to control the exhaust fan (fan switch).
