Product Features:
1.Equipped with an advanced electromagnetic balance force sensor,
ensuring high-precision measurements and excellent repeatability
for consistent results.
2.The 5-inch widescreen touchscreen integrates real-time display of
ambient temperature, current tension, peak tension, equivalent
tension, and more, offering intuitive operation and clear data
visualization.
3.Features a dual-test design supporting both platinum plate and
platinum ring methods, allowing users to select either method
individually or employ both simultaneously for versatile testing.
4.Fully automated workflow eliminates human error entirely:
auto-detects liquid interfaces, plots tension curves in real time,
locks peak values, displays direct readings on-screen, and stops
measurements autonomously, reducing manual intervention.
5.Enables full-range automatic calibration, supporting coefficient
adjustment via standard weights, distilled water, and anhydrous
ethanol for precise instrument tuning.
6.Quiet motorized sample stage with touchscreen-adjustable lifting
speed (1–300 mm/min) ensures smooth, controlled movement during
testing.
7.Quick-release bracket for platinum accessories facilitates easy
installation/removal and allows on-demand force calibration with
standard weights to maintain accuracy.
8.One-touch tare function guarantees stable, drift-free
measurements without zero-point fluctuations.
9.Automatic temperature compensation converts readings to tension
values at 20°C based on water/ethanol references, ensuring
standardized results.
10.Data acquisition software is compatible with all Windows systems
(WIN 7/8/10/XP), supporting seamless data collection and
management.
11.Complies with multiple international and national standards,
including GB/T6541-86, ISO1409-1995, GB/T22237-2008, and more,
ensuring regulatory compliance.
12.Patented instrument design delivers technological uniqueness and
a competitive edge in measurement accuracy and functionality.
