cone-shapeCalorimeter

DX-8348 cone-shapeCalorimeter

Ⅰ、E standard：met the standard required testing method of GB/T16172-2007《the testing method for building materials heat release speed》andISO5660-1：2002《Testmethodforheatreleaserateofbuildingmaterials》.

Ⅱ、range of using：caculate the oxygen consumption through the oxygen concentrations in airflow of combuston produts, as well as the heat release speed of the combustion produts whiling aflame . The heat release speed of material is also an important parametric for material combustion capability，it is quiet important to measure the heat release speed of aflame material accurately for forecasting damage by fire disaster and the process for prevent flame retardant.

Ⅲ、working conditions：
1、working envirenment tempreture：0℃-50℃
2、working envirenment humidity<80%
3、power supply：380V±50%,50Hz±2%

Ⅳ、main capability prrameter：
1、radiate conic：heating capacity：5Kv,radiate strength：100Kw/m2,allocate three thermocouple mesure temperature.
2、exhaust system：made of centrifuge air-blower,exhaust fume collecting hood, blower’s in-breath and out-breath pipe , and the orifice meter.
The maxmum placement amount of the sample box：up to 100mm*100mm*50mm。
3、exhaust capactiy：0.012m3/s~0.035m3/s(adjustable）
4、timing amount resolution：1Saverages error <1s/n
5、oxygen Analyzer：Siemens paramagnetic oxygen analyzer，02measure range：0-25%
6、e with sampling pump and the smoke dust filter
7、gas flow use imported high flow controller
8、ignition voltage：220V，bipolar electrode，insure the safty of testing.
9、exhaust smoke flow：smoke exhaust fan adopts frequency conversion control，it can achive the exhaust smoke range at 0.012m3/s~0.035m3/sautomaticly。
10、control system：use Detectioncontrol system and ZWH4500gatheringcontrol card.

，it can achive Automatic Digital Data Ac, processing, data save and export measure report.
