Functional Features
Embedded processor with Windows CE operating system.
8-inch LCD touchscreen for real-time display of test status.
High-resolution photosensitive sensor with fast response time, capturing flash or explosion events and outputting detection signals.
Dual-channel digital flow meter for highly accurate gas flow control, ensuring precise mixing of test gas and air.
Equipped with an online gas sampling channel for quantitative analysis via GC/MS or other instruments.
High-precision photosensitive sensor monitors light intensity inside the reaction tube in real time, automatically determining the flammability of the gas at that concentration and providing combustion rate data.
Automatic determination of combustion performance during testing, with control over gas concentration ramping.
Reaction chamber constructed with double-layer tempered glass for operator safety.
Fully automated testing process without manual intervention, supporting parameter setting, data storage, and report generation.
Accessories
(1)Gas Sampling Chamber: Holds the gas sample securely for testing.
(2)Sensors/Detectors: Measures flammability, toxicity, or explosive potential.
(3)Control Unit: Regulates temperature, pressure, and gas flow during tests.
(4)Data Interface: Connects to PC or display for recording and analysis.
