Incorporates an advanced electromagnetic balance force sensor, guaranteeing high precision and consistent repeatability.
The 5 - inch widescreen touchscreen offers an integrated display of ambient temperature, real - time tension, peak tension, equivalent tension, etc., providing an intuitive and user - friendly operation experience.
Features a dual - test design that supports both platinum plate and platinum ring methods, allowing users to choose either one separately or use them simultaneously.
With a fully automated operation process, it completely eradicates human errors. It can automatically detect the liquid interface, draw the tension curve, lock the peak value, display the readings directly on the screen, and stop the measurement autonomously.
Enables full - range automatic calibration, and accepts calibration using weights, distilled water, and anhydrous ethanol to fine - tune the instrument coefficients.
Equipped with a quiet, motor - driven sample stage, whose lifting speed (ranging from 1–300 mm/min) can be conveniently adjusted via the touchscreen.
The quick - release bracket for platinum accessories makes for easy installation and removal, and also allows for on - the - fly force calibration with standard weights.
The one - touch tare function ensures stable measurements without any zero drift.
Automatic temperature compensation adjusts the readings to the tension values at 20°C, based on references of water and ethanol.
Comes with data acquisition software that is compatible with all Windows operating systems, including WIN 7, WIN 8, WIN 10, and WIN XP.
Meets various standards such as GB/T6541 - 86, ISO1409 - 1995, GB/T22237 - 2008, SH/T1156 - 95, ISO6295 - 1983, JB/T18396 - 2001, GB/T5549 (ISO 304 - 1985), and more.
Boasts a patented design, ensuring its uniqueness and technological edge.
