QBZY automatic surface interfacial tension meter

QBZY automatic surface tension meter with high precision, high stability of force measurement system, microcomputer control system, platinum plate / platinum tour measuring device component. The instrument of advanced design, reasonable structure, automatic measurement, convenient operation and easy maintenance; sample automatic lifting, full range to tare (reset). Full automatic range correction; the instrument repeatability is very good, the test results are accurate and reliable. The test data of liquid crystal display, through the RS232C interface output.

With the sample pool thermostatic apparatus and sample temperature measuring device, to meet different test requirements.

QBZY automatic surface interfacial tension meter

Main features:

1 platinum plate, platinum ring test method used;

2 fully automatic measurement, platinum plate test, the display value is the surface tension value;

3 the use of white gold test method, display the value of maximum force automatic locking values of samples, and then through the calculation software with the calculation of surface tension values or data processing software automatically by computer;

4 platinum ring size: the wire radius is 9.55mm, the radius of the ring is 0.185mm, the circumference of the ring is 60mm;

5 the use of platinum gold test methods, fully in accordance with the following domestic and international standards:

Determination of surface tension of 22237-2008 GB/T surface active agent

JB/T 2002 – 9388.

Determination of surface tension of JB/T 18396-2001 natural latex Tour de France

Determination of the surface tension of 1156-95 SH/T composite latex

GB/T 86 – 6541 oil product oil to water interfacial tension measurement method (ring method)

1409-1995 ISO plastics, rubber, polymer dispersions and the determination of surface tension of latex

Determination of the interfacial tension of the mineral oil in 6295-1983 ISO petroleum products (ring method)

GB/T 5549 (ISO304-1985) was used to determine the surface tension of the membrane method

And ASTM, D1417, ISO14090-82, EN14370, ZB2025-93, GB2960- 82, GB6541-86, etc.

6 automatic measurement, to avoid human error;

7 full range automatic calibration, data accurate and reliable, good repeatability;

8 a key to zero, the moment is complete, zero bit stable without drift;

9 the use of the international advanced platform driven technology, no vibration and noise;

10 the instrument structure is reasonable, independent work, without any additional equipment (such as external computer, etc.), but also can be matched with the computer data processing;

11 when using platinum plate, can measure the surface tension of liquid in real time, and the surface tension will change with time varying with time. It is very practical;

12 the surface tension of the high viscosity liquid sample can be automatically tested by using the platinum plate test;

13 can measure the interfacial tension between the non – mixed liquid such as: Oil / water interface;

14 data processing software: automatic acquisition test curve, curve can automatically enlarge, can access, can be printed. Can carry out a plurality of test curves, can automatically calculate the surface tension values of the platinum gold method;

15 accuracy correction function: with the 2 distilled water and ethanol as the standard, the overall testing error of the instrument is automatically calibrated, which can ensure the accuracy of the instrument is in the factory;

16 USB data output interface, easy to connect with notebook computer;

17 with a variety of temperature control options, to meet different test requirements;
