Product description
The CIT10-10S enclosed-space aerosol ignition tester evaluates aerosol flammability in a closed or restricted volume in accordance with UN 'Recommendations on the Transport of Dangerous Goods — Manual of Tests and Criteria' (section 31.5) and GB/T 21631-2008. The instrument reproduces confined-space conditions to determine whether ignition, flash or explosion occurs when an aerosol is discharged.

Instrument overview
The system comprises a display/control unit and a detection module. The detection module is a cylindrical vessel with integrated optical sensors and a high-precision thermocouple to detect ignition or knocking events. The display/control unit features an LCD for real-time monitoring and test control. Aerosol cans are positioned and actuated automatically; the device supports vertical and inverted orientations.
