5、電源:220V   50H

6、主機(jī)外形尺寸:300×300×400

表面、界面張力儀儀器特點(diǎn):

1、采用微機(jī)控制,能夠顯示實(shí)時(shí)力值變化曲線,該曲線用來(lái)分析液體在被鉑金環(huán)拉伸過(guò)程中界面或表面性質(zhì)變化情況。該曲線以圖片的方式保存,并能夠和試驗(yàn)報(bào)告一起綜合打印,也可以獨(dú)立復(fù)制和打印。

2、測(cè)試方便,便于保存測(cè)試數(shù)據(jù)和打印試驗(yàn)報(bào)告。測(cè)試數(shù)據(jù)已數(shù)據(jù)庫(kù)的方式保存到軟件中,每一次測(cè)試都能夠長(zhǎng)期保存,并對(duì)統(tǒng)一液體的多次測(cè)試自動(dòng)求平均值,得到平均結(jié)果。

3、PC機(jī)與儀器通過(guò)串行口通訊,連接簡(jiǎn)單,不需要數(shù)據(jù)采集卡,不需要改動(dòng)PC機(jī)硬件,對(duì)系統(tǒng)要求低,只要有串行接口能夠運(yùn)行WindowsXP以上系統(tǒng)的微機(jī)均可使用。

4、儀器和軟件雙向控制,儀器可以獨(dú)立工作。

Jyw-200a microcontroller automatic surface/interface tensiometer

Micro - controlled automatic surface and interface tensimeter, which conforms to JB/T9388 and ISO1409 standard, is a kind of instrument for testing liquid surface and interface tension by physical method.

The surface and interface tensimeter adopts microcontroller technology, which is simple and intelligent.

Automatic zero, real-time display force value and curve, peak holding and other functions;

The experimental results are automatically corrected and automatically averaged;

The results can be easily displayed, stored and printed.

To test the interfacial tension value of electric oil in the electricity and water sector to strengthen the supervision over insulating oil quality.

The surface tension value of various liquids can be tested in oil, chemical, scientific research and other departments to enhance the analysis of various liquids.

Main technical parameters of surface and interface tensimeter:

1. Measuring range: 0 -- 200.0mN/m

2. Resolution: 0.01mN/m

3. Measurement method: ring method

4. Relative error of the display value: < / -1%

5. Power supply: 220V 50H

6. Main frame size: 300 x 300 x 400

Characteristics of surface and interface tensiometer instruments:

1. With microcomputer control, the real-time force value change curve can be displayed, which can be used to analyze the changes of the interface or surface property of the liquid during the stretching process of the platinum ring.

The curve is saved in the form of pictures and can be printed together with the test report. It can also be copied and printed independently.

2. Easy to test, easy to save test data and print test report.

The test data is saved to the software in the way of database. Each test can be saved for a long time, and the average result is obtained by the average test of the unified liquid.

3, PC and instruments through the serial port communication, simple connection, don't need a data acquisition card, do not need to change the PC hardware, the system requirements is low, as long as there is a serial interface to be able to run more than the Windows xp system of microcomputer can be used.

4. The instrument and software are controlled in two directions, and the instrument can work independently.
