Fire testing cone calorimeter

Fire testing cone calorimeter

•      Structural characteristics

1.1. Integrated design of 19 inch standard cabinet, beautiful and elegant, easy to operate, avoiding interference factors such as vibration
1.2 Cone Heater - Within a truncated cone, 230V, 5000W, heat output ranging from 0 to 120 kW/m2
1.3. The entire testing process is controlled by a computer with a 19 inch touch screen
1.4. It has functions such as automatic ignition, automatic timing, automatic gas cut-off and shutdown, and is equipped with online testing camera function to capture the entire combustion testing process; The computer software is equipped with a video detection interface and can automatically save to the computer.
1.5. Three K-type thermocouples and a three-stage PID temperature controller are used to regulate the temperature
1.6. Automatic Splitting Gate - Protect the sample area before testing to ensure stable initial quality measurement. Operators may have additional time to perform system testing before testing begins. For flammable samples, if there is no opening and closing mechanism, it is easy to burn prematurely. This extra time is very important for the operator
1.7 Sample holder - sample size 100mm x 100mm, thickness not exceeding 50mm;
1.8. Possess expansion functions/interfaces for subsequent combustion equipment and heat release measurement systems
1.9. The internal packaging of the gas analyzer contains CO ₂/CO standard gas, which can be automatically calibrated at full capacity through computer software without the need for external standard gas
