Setting up

IIQ seriesThe main features of the fully automatic surface tension meter (professional model) are:

Q series (Q2000, Q1000, Main features of Q500 (three models):

The Q series tensiometer provides multiple measurement methods, including traditional platinum plate method (Wilhelmy) and platinum ring method (DuNo ü y), as well as optional density accessories, to accurately measure the density of the tested sample.

The platinum ring can be set to one or multiple stretches (customizable). No calculation required, fully automatic measurement.

★ Built in electronic level with operation instructions. The level of the sample stage can be adjusted to ensure accurate measurement of the tension meter.

The spacious sample room is equipped with glass sliding doors, which are very easy to operate and can also prevent the influence of indoor air convection on stable measurements.

The built-in measurement program can control the lifting of the sample stage to ensure that there is no human interference during the measurement process, and the operating speed can be adjusted according to experimental requirements.

The electromagnetic force sensor and supporting control system have temperature compensation function, which can effectively reduce the impact of long-term drift.

★ Achieve simple and intuitive operation and use through a 7-inch touch screen. Intuitive operation on the touch screen is a major feature of the new generation of tensiometers, allowing for easy control of the sample stage and other components both before and during measurement.

★ Built in measurement data management menu, convenient for viewing data and supporting external printer operation. All measurement data files can be transferred via USB flash drive and converted into Excel files for easy management, recording, and organization of measurement data.
