Smoke Density Tester

Product Features:

Smoke Density Tester features a 304 stainless steel exterior with high-end spray coating; utilizes PLC programming + touchscreen operation for fully intelligent control, enabling true networking and remote control capabilities; optional TFT true-color LCD display; supports customized user-friendly interface upgrades to achieve internationally comparable results.

Smoke Density Tester complies with ASTM D2843 (US) and GB/T 8627 standards for testing smoke density from burning or decomposing building materials. It evaluates smoke density by measuring the loss of light flux caused by solid particles in smoke reflecting light.

Product Parameters:

1: Test chamber constructed with 304 stainless steel and high-end spray-coated exterior, resistant to corrosion from combustion smoke, significantly extending product lifespan;

2: White "EXIT" sign with red letters installed at chamber base allows operators to observe clarity of samples through transparent viewing window post-test;

3: Light source uses incandescent lamp, photoelectric sensor employs silicon photodiode with cosine correction function, equipped with color filter to remove UV/IR light undetectable by human eyes, achieving optimal eye-response matching;

4: Main burner delivers flame impact at 276KPA pressure, supplemented by auxiliary burner for igniting drips;

5: Auxiliary burner operates at 138KPA pressure to further combust molten drips;

6: Standard software displays 15s-interval light transmittance values, plots transmittance curves, and calculates SDR smoke density value (smoke accumulation index) post-test;

7: Software can synthesize test reports from three samples to generate SDR smoke development curve;

8: Smoke density measurement range: (0~100)%;

9: Calibration error with standard filter ≤ 3%;

10: Bunsen burner pressure: (210±5) KPa (adjustable);

11: Flame application time: 4min (presettable);

12: Burner: Bunsen type, 260mm length, 0.13mm nozzle diameter, 45° angle to chamber;

13: Photoelectric system: 15W bulb with 6V operating voltage;

14: Receiver: Silicon photocell, 0% transmittance = no light, 100% = unobstructed light passage;

15: Main burner pressure: 276KPa (adjustable);

16: Processed focal length: (60~65)mm;

17: Gas source: 85% propane (user-provided), with built-in gas leakage alarm system;

18: Dimensions: 750mm(W)×350mm(D)×1200mm(H), exhaust port Φ100mm;

18: Power supply: AC220V±10% 50HZ
