Precision of heat flow meter is 3%,repeatability is +0-0.5%,attached a adjust report can be date back to NIST.

18.)supply portable cooling water system.when use heat flow meter ,users do not need to tap and equipped with water.

19.) In order to calibrate the response of the whole test system, a square hole with a square hole and a square yellow copper tube is used as the calibration burner for measuring the C- coefficient values.

20.) Data acquisition system should be able to record the oxygen analyzer, orifice meter, thermocouple and other instruments of the output.

21.) Equipped with software operating system, the test results include: heat release rate, gas flow rate, C coefficient, sample time and time, total oxygen consumption, total smoke, mass loss rate, total heat release, effective combustion heat, carbon dioxide emissions and carbon dioxide emissions.

Soft ware instruction of cone calorimeter:

1.) Set in order to calibrate the sensor, including the oxygen analyzer, carbon dioxide analyzer, carbon monoxide analyzer, micro pressure difference sensor, smoke density measurement system, weighing device, mass flow control single or double point calibration, in order to obtain the best linear;

2.) C- coefficient calibration, the software can automatically set the C coefficient measurement of gas flow, such as 1KW, 3KW or 5KW, the computer system automatically calculates the ISO 5660 C coefficient and the average C coefficient, and can save the record;

3.) The software can automatically generate the C- coefficient log, which is convenient for the user to view the history of the cone calorimeter, and to identify the accuracy and stability of the system;

4.) The system can automatically calculate the delay time of the oxygen analyzer, the carbon dioxide analyzer and the carbon monoxide analyzer, which is convenient for the synchronous calculation

5.) Status check interface, the working state of the various sensor components of the instrument can be clear at a glance;

6.) Can record the work value of each sensor, including micro pressure difference sensor, chimney temperature, oxygen analyzer, carbon dioxide analyzer, carbon monoxide analyzer;

7.) The report template is EXCELL format, which can display graphics and numerical model.

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.
