Introduction: This tester is used to evaluate the flammability of aerosol in closed or restricted space. In line with the United Nations Recommendations on dangerous goods transport, test and standard manual, 31.5 closed space ignition test and GB/T 21631-2008 "dangerous goods sprays closed space ignition test method". characteristic: 1) Embedded processor and windows CE operating system are adopted; 2) 8 inch LCD touch screen can display the test status in real time; 3) Two working modes, standard mode and custom mode, are integrated; 4) spray automatically spraying, and the spray tank clamping device can automatically realize the vertical and inversion of the tank. 5) automatic timing of spray time. 6) The dual detection module of pressure sensor and nanosecond photosensitive sensor can automatically detect whether the flame is burning or exploding in the closed space; 7) Ventilation system is provided to timely discharge the smoke and unlit aerosol in the barrel to ensure the accuracy of the test and the safety of the laboratory personnel; 8) The test process is fully automated, without manual intervention, supporting parameter setting, data storage, viewing reports and other functions; 9) Equipped with temperature and humidity module, it can monitor the temperature and humidity of the test environment in real time. Technical parameters: Working environment: (- 5 ~ 45) ℃, < 95% RH Ambient temperature measurement range: - 10 ℃ ~ + 60 ℃ Measurement accuracy of ambient temperature: ± 0.5 ℃ Environmental humidity measurement range: 5% RH ~ 95% RH Measurement accuracy of ambient humidity: ± 5.0% RH Combustion detection response time: ≤ 6ms Pressure measurement (differential pressure) range: - 5 kPa ～ 5 kPa Pressure measurement accuracy: ± 0.1% FS Timing display resolution: 0.1s Ignition flame: candle flame in accordance with the standard, adjust the height of cushion pillar by 20 mm / piece Cylindrical vessel size: Ф 600mm × 720mm Positioning of aerosol tank: the aerosol tank can be turned over automatically Compatible spray tank size: height (120~400) mm, diameter (30~80) mm Distance between cylindrical vessel and spray tank nozzle: (25~100) mm adjustable Accumulating fluid: the residual liquid ejected from the spray tank can be extracted and processed at any time.
