220V Flame Retardant Test In Fires Heat Release Rate Checking Thermal Conductivity Lab

Product Application

The name Cone Calorimeter is derived from the conical heater as used by Dr. Vytenis Babrauskas to inspect test specimen(100×100) with flux up to 100/ for the bench scale oxygen depletion of his development.

ISO Solution Fire Testing Equipment Cone Calorimeter 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.

ISO Solution Fire Testing Equipment Cone Calorimeter, as properly sized for lab use, is designed to enable auto operation of all units connected with DAQ(Data Acquisition) Program so that user can conveniently perform test. Also, it reduces installation space and automatically advances test with the 17inch Touch Screen. This tester fully meets the international standard.

Structure of cone calorimeter

1.)The combustion chamber: the conical heater, the 10KV ignition device, the control circuit, the windshield, etc..

2.)Oxygen analyzer: Servomex analyser, oxygen analyzer can accurately test the content of oxygen in the air pipe in the time of the change, and then by the instantaneous oxygen concentration and oxygen consumption principle to determine the heat release of the material.

3.)Load table: a device for measuring the quality of the sample, which can accurately record the mass change of the sample in the process of combustion

4.)Smoke measurement system: He Ne laser emitter and double electron beam measuring device, which can be used to determine the specific extinction area (SEA) of the smoke in the smoke pipe.

5.)Ventilation system: the ventilation system is a sample of the combustion products from the combustion chamber to the atmosphere in the device

6.) Other improvement equipment: according to different needs, can also add other analysis device, such as the analysis of the combustion products, can increase the infrared spectrum analysis device; if the temperature distribution in the sample, the corresponding thermocouple or infrared imaging device.

7.) Auxiliary equipment: auxiliary equipment includes microcomputer processor, heat flow meter device, removing CO2 and H2O (gas), etc..
