Q2000&Q1000&Q500 Automatic surface tensiometer
Product feature
1.High quality core components ensure accurate measurement, each tensimeter is equipped with a high-precision mechanical electromagnetic force sensor, the highest precision of surface tension up to 0.001 mN/m.
2.Tensimeter adopts 7 inch touch screen, all information is clearly displayed on the screen and the operation is completed.The machine does not need a computer when operating, can be used, support Chinese and English exchange display.
3.A tractor serves several purposes.
The tensimeter can meet the plate/ring method measurement, data direct reading does not need to calculate, plate/ring design size and process meet domestic/foreign standards.
4.Liquid density measurement
According to the buoyancy principle, the density of the tested sample can be accurately obtained by immerging the standard volume part in the test sample.
5.Measurement space with LED lighting
The lighting device in the spacious measurement area can illuminate the sample surface and the measuring body, so that the sample positioning is more accurate.
6.A wealth of optional accessories
Provide a variety of accessories to meet often different test needs.

Measurement methods
★ Q series tensiometers provide a variety of measurement methods, including the traditional platinum plate method (Wilhelmy) and platinum ring method (DuNouy), as well as optional density accessories to accurately measure the density of the sample under test.
★ Platinum ring method can be set one stretch or multiple stretches, can be set by yourself.No calculation, automatic measurement.
Built-in electronic level, with operating instructions.It can accurately adjust the level of the sample table to ensure the accurate measurement of the tensimeter.
★ The spacious sample room is equipped with transparent glass sliding door, which is very convenient to operate and can prevent the influence of indoor air flow on stability measurement.
★ The built-in measuring program can control the lifting of the sample platform to ensure no human interference in the measuring process. The running speed can be adjusted according to the requirements of the experiment and can be repeated accurately.The use of dynamic and fluid actuation eliminates vibrations that can have negative effects.
★ Electromagnetic force sensor and matching control system, temperature compensation function, can reduce long-term drift to a minimum.
★ Simple and intuitive operation through 7-inch touch screen.Intuitive operation on the touch screen is a major feature of the new generation of tensimeter, no matter before or during the measurement, can easily control the sample table and other components.
Built-in measurement data management menu, easy to view data and support external printer operation.All measurement data files can be transferred through THE U disk and converted into Excel files for convenient management, recording and sorting of measurement data.
Application field
