HOPU HZL Series automatic tension tester apply to GB/T6541 Standard Test ASTM D971 ,it can test kinds of liquid surface tension and boundary surface tension.Based on ring method (platinum ring method), the surface tension (liquid gas interface) and interfacial tension (liquid liquid interface) of various liquids are measured. This method has the advantages of simple operation and high accuracy and is widely used. It is widely used in power, petroleum, chemical, pharmaceutical, food, teaching and other industries.
Inter molecular Forces formed liquid surface tension.Numbers of tension reflect on liquid sample's physics and chemical properties, it is one of the most important index to product quality.
1.Large color LCD screen, English prompt, menu operation, fully automatic testing.
2.Automatic temperature compensation within 25℃ eliminates the influence that the temperature imposes on the tension value.
3.Functions of auto correction, auto testing, calculation, results displaying, and storage under power off circumstance.
4.The main body is equipped with hurricane globe, which lessens the influence outer matters impose on testing results.
5.Automatic lift of the lift platform ensures a stable environment and high accuracy.
6.It adopts enclosed magnetic pot type sensor and multi-point calibration of uniform space technology, which improves the repeatability and reproducibility of the results.
7.It can work independently and can also realize network management via connection with laptops or microcomputers through USB interface.
8.Tester program can be updated accordingly if related national standard revised.
Main technical features
The instrument adopts large LCD screen and blank button, so it is automatic, reliable, and simple and with good repeat ability. Turn on the instrument and operate the instrument as per the prompt of menu, and you can complete the test as per the prompt.
The instrument has function of automatic temperature compensation, clock control, printing, and automatic average value calculation. It can connect to a computer through RS232 interface. You can also send the test data to a handheld computer for analysis. It is the best choice to make determination for interfacial tension test.
