三、主要特點(diǎn)

儀器外形及結(jié)構(gòu)如上圖所示。與傳統(tǒng)的康拉特遜殘?zhí)繙y(cè)定儀相比本儀器具有以下幾項(xiàng)特點(diǎn)：

1、只需少量的試樣即可進(jìn)行試驗(yàn)：

試樣量（g）     5.0±0.5       0.5±0.1      0.15±0.05

2、可同時(shí)測(cè)定12個(gè)樣品。

3、采用氮?dú)獗Ｗo(hù)氣流，確保試驗(yàn)條件不變能夠獲得良好的重復(fù)性和再現(xiàn)性。

4、采用氣管導(dǎo)出法排放試驗(yàn)尾氣，同康氏法測(cè)定儀相比對(duì)實(shí)驗(yàn)場(chǎng)所的要求更加自由靈活。

5、采用軸流風(fēng)機(jī)進(jìn)行冷卻，有助于降低儀器溫度。

6、操作僅需按動(dòng)“啟動(dòng)”鍵，一切均由儀器自動(dòng)進(jìn)行測(cè)試，正常時(shí)無(wú)需任何操作和判斷，試驗(yàn)結(jié)束后，蜂鳴器提示試驗(yàn)結(jié)束。

7、顯示直觀明了，方便觀察。

PCT17144 inligent micro carbon residue tester
One, overview
The apparatus is in accordance with the GB/T 17144 "petroleum products - Determination of carbon residue," "ASTM D4530" and "ISO 10370:1993" standard requirements of design and manufacturing. Has the advantages of beautiful appearance, convenient operation, the test results and the GB/T268 (Kang's method) consistent test results.
Two, the main technical parameters
1, the input power supply: AC 220V + 5% 50Hz
2, the heating power: 950W
3, temperature 500 DEG C:
4, temperature control precision: - 2 DEG C
5, most can be used as specimen number: 12
6, working pressure: 0.15Mpa
7, air pressure: the pressure minimum level 2MPa, two level of maximum pressure for 0.5Mpa
8, the nitrogen flow rate: 150mL/min 600mL/min (according to GB/T 17144-1997)
9, working time: about 120min
10, the working environment temperature: 25 C
11, the environmental relative humidity: <85%RH
12, size: 380 * 410 * 570mm (length * width * height)
Three, the main features
The shape and structure of the instrument are shown. And Kanglatexun carbon residue tester compared with the traditional instrument has the following features:
1, only a small amount of sample can be tested:
The amount of residual carbon (%) < 1 > 1-5 > 5
Sample size (g) 5 + 0.5 0.5 + 0.1 0.15 + 0.05
2, the simultaneous determination of 12 samples.
3, protected with nitrogen gas flow, ensure the constant test conditions to obtain good repeatability and reproducibility.
4, use tracheal derived method of emission test exhaust, with Kang's method determination instrument compared to the experimental location requirements more free and flexible.
5, adopt a shaft for cooling flow fan, helps to reduce the temperature of the instrument.
In 6, operation only needs to press the "start" button, all are the automatic test instrument, the normal without any operation and judgment, after the test, the buzzer tip end test.
7, display intuitive, convenient for observation.
