19.) supply portable cooling water system.when use heat flow meter
,users do not need to tap and equipped with water.
20.) 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.
21.) Data acquisition system should be able to record the oxygen
analyzer, orifice meter, thermocouple and other instruments of the
output.
22.) 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.
Description:cone calorimeter tester
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
