DX-8348coneshapeCalorimeter

Ⅰ、Equipment standard：met the standard required testing method of GB/T16《the testing method for building materials heat release speed》and?ISO5660-1：2002《Test?me?thod?for?heat?release?rate?of?building?materials》.
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、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：1S???averages error <1s/n
5、oxygen Analyzer：Siemens paramagnetic oxygen analyzer，02 measure range：0-25%
6、equipped with sampling pump and the smoke dust filter
7、gas flow use imported high quality 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~0.035?m3/s automaticly。
10、control system：use Detection control system and ZWH4500??gathering control card.
，it can achive Automatic Digital Data Acquisition, processing, data save and export measure report.
11、the divice adopt both manuel and automatic control style, it can cutover to manuel style operation.
12、the deivce adopt universal casters，it is convenient for users to move the device.
13、exhaust system ：?adopt frequency conversion blower control the exhaust flow, realize the automatically controll through microcomputer; use integrated orifice meter to measure the exhaust blow and make the exhaust blow more correct.
14、 weighing devices ：use high accuracy weighing sensor，which reacts quickly in short time , weighing accuracy reach 0.1g，accuracy 0.01g
15、imported diaphragm pump，flow rate：33L/min，vacuum：700?㎜Hg，pressure：2.5?bar。
16、imported smoke dust filter, the filter head made of solid PTFE, inside is 0.5um PTFE filter materials.
17、imported moisture filter, the filter head made of solid PTFE，the bottom liquid can be exhausted through peristaltic pump.
18、imported Taikang compressor style cooled condenser, cooling capacity 320kJ/h， the stability of Dewpoint 0.1，Dewpoint static changes 0.1K，protect level IP20。
19、device control system：adopt computer control and date processing, computer measurement and control system is consit of tracking and command soft ware, hard ware, computer and printing machines.....
20、tracking and command software：it can work under many kinds of operate systems of windows, testing date adopt managing date base method, to achive collecting and processing the date from testing, as well as data save and exprot testing report, and automaticly save all the testing data.
