High-performance weighing sensor with electromagnetic force balance principle has accurate measurement and excellent repeatability.
Platinum plate method and platinum ring method are combined together. Except for the manual operation of the lifting platform, the rest are the same as the IT-800M series automatic surface/interface tension tester. Therefore, it has a very high cost performance.
Main Features:
1. Precision displacement transmission mechanism,
manual control of the lifting and lowering of the
sample stage,can be fast or slow, very convenient.
2. Full-scale one-key clear, instant completion,
zero-free drift.
3. Full -scale automatic correction: accurate and
reliable data, excellent repeatability.
4.Unique accuracy and automatic calibration
function, convenient and practical, keep the instrument in an accurate state for a long time.
5. Unique temperature automatic compensation function, data measured at different temperatures can be automatically corrected to the measured value at 20 ºC.
6. Platinum plate test, the displayed value is the surface/interface tension value of the sample, no need to recalculate; During the test of platinum ring, it can keep the peak value, which automatically converted into the surface / interface tension value through Excel calculation or data processing software.
7. Compact structure and independent operation.
8. It can measure the change of the surface tension of sample due to different time (especially in the platinum plate test mode when there are surfactants or volatile substances)
9. Automatically measure medium and high viscosity liquid samples and get accurate balance results (limited to platinum plate test mode).
10. It can measure the interface tension between non-mixed liquids such as oil/water interface
10. The selected constant temperature options (constant temperature bath and constant temperature cell) can accurately control the temperature of the tested sample.
11. Standard data processing software: automatically calculate the surface/interface tension in the platinum ring measurement mode, automatically collect test data, display the test curve in real time, and be accessible and printable.

Note:
1. Accuracy error and repeatability error refer to the difference between the test standard material (2 times distilled water or pure ethanol) and the literature value.
2. To keep the sample at constant temperature, and the corresponding constant temperature bath and constant temperature cell are required.
3. To achieve the constant temperature range of the sample, the corresponding bath and sample thermostat cup are required.

Introduction of Accurate Auto-calibration
At present, there are many domestic manufacturers of surface / interface tensiometer, but which seldom have similar advanced technology as imported "accuracy automatic calibration".
The so-called "accuracy automatic calibration" is to automatically correct the overall error of the actual measurement standard sample of the instrument (the theoretical value of the surface tension of secondary distilled water at 20 ºC is 72.75mn/m and the theoretical value of the surface tension of pure ethanol at 20 ºC is 22.3mn/m), so as to ensure that the instrument can meet the requirements of the technical parameters.
Typically, surface/interface tension tester have full-scale calibration, which is done with a weight equivalent to the maximum range (eg 200mN/m, 400mN/m or 600mN/m). No matter which company adopts the method, it can only calibrate the circuit part of the instrument. Full-scale calibration is necessary for measuring instruments, but not comprehensive: because a full-scale calibrated instrument does not mean that actual measurement of the sample is accurate. This is because the measurement error of the key sensing element, the platinum plate or the platinum ring, is not taken into account.
Similar instruments sold on the market, it is difficult or unlikely to reach 0.1mn/m or 0.03mn/m only by manual calibration,due to lack of "accuracy automatic calibration" function.
