Technical features:
1. Made of 1.5mm thick imported brushed stainless steel, heat-resistant and smoke-resistant, easy to clean;
2. The flame height adjustment is controlled by a precision rotor flowmeter, which ensures stable and easy adjustment of the flame.
3. Color touch screen display operation, Chinese and English interface, menu-based operation mode;
4. The core components use STMicroelectronics’ 32-bit multifunctional motherboard to process data;
5. Stepper motor motion control ensures smooth and precise movement of the burner;
6. The burner is made of B63 material, which is corrosion-resistant, non-deformable, and non-embroidered;
7. Automatic electric ignition (replacing manual ignition mode);
8. Automatically cut off the gas source when the ignition time is up (replacing the manual shutdown function);
Testing Principles
This instrument is designed as a whole box and mainly consists of a control system and a combustion chamber. The sample is installed on a sample holder tilted at a 45 ° angle in the combustion chamber, with the flame nozzle close to the sample. After igniting the sample with a flame for a specified time, it returns to observe the combustion situation of the sample and the spread speed of the flame on the sample, and evaluate the ignitability and flame spread performance of the sample.
