Instrument introduction
The cone calorimeter is derived from the oxygen consumption of a rectangular sample (100mm×10mm) tested by Dr. Vytenis Babrauskas at a heat radiation value of 100KW/m2.
The cone calorimeter is based on the principle of oxygen consumption of material combustion. The heat released per 1Kg of oxygen is about 13.1MJ. It measures the heat release of the material, ignition time, oxygen consumption, CO and CO2 production, and the flow of combustion gas.
The cone calorimeter strictly conforms to the size of the laboratory, and the automatic control unit designed by the test software is convenient for the user to operate. In addition, he uses a 17-inch touch screen computer, which is fully compliant with international standards.

2.Integrated test body and 19 inches analysis cabinet, embedded PC 15 Inch Touch screen computer, for the whole control and automatic testing.
3.Conical heater rated power 5000W, the heat output of 0 ~ 100kW/m2, using PID temperature controller, while the radiation cone can be horizontal or vertical.
4.Exposed to the central part of the surface of the sample 50 x 50mm range, radiation at the center of the deviation is not more than 2%.
5.The sample weighing range 0 ~ 3000g; accuracy: 0.1g.
6.Auto Split Shutter automatically opened to transmit radiation to the sample.
7.ABB EL3020 Paramagnetic oxygen analyzer, using the method of paramagnetic change to measure the concentration of oxygen in the gas. Concentration range of 0-25%.
8.Smoke density analysis using laser system, the system consists of a 0.5mW He Ne laser, the main detector and auxiliary detector.
The exhaust system consists of the fan, the smoke collection cover, the exhaust pipe and orifice plate flow meter and so on. Exhaust fan flow rate of 0 ~ 50g/s, precision 0.1g/s.
9.Ring sampler have been installed from the smoke collecting hood at 685 mm, with 12 holes.
10.The exhaust flow rate should be determined by measuring the pressure difference on both sides of the sharp edge orifice 350 mm above the fan, the inner diameter of the sharp
edge orifice plate is 57mm + 1mm.
11.ABB SCC-S Gas sampling system comprises sampling pump, filter, cold trap, waste water discharge, water filters and CO2 filters;
Portable water cooling system without need for waterworks and plumbing when using the Heat Flux meter (for ISO 5660).
12.In order to calibrate the response of the whole test system, the use of a square opening brass calibration burner, used to measure the value of C- coefficient.
13.The data acquisition system be able to record oxygen analyzer, orifice meter, thermocouple and other instruments of the output.
Application: Suitable for testing the heat release rate of building materials, Rail,Wire Cable
Product Details of the Cone Calorimeter
The name of Cone Calorimeter is derived from the conical heater as used by Dr. Vytenis Babrauskas to inspect test specimen (100mm x 100mm) with flux up to 100kW/m2 for the bench scale oxygen depletion of his development. Cone Calorimeter test is based on the theory that pure combustion calories are in proportion to a necessary amount of oxygen for combustion and 13.1 MJ/kg is generated whenever oxygen 1kg is consumed, and heat emission, ignition time, oxygen consumption, CO and CO2 generation, and flow of ignited gases as generated from test materials are measured.
