Product Features:
1.Utilizes advanced electromagnetic balance force sensor for high-precision, repeatable measurements.
2. 5-inch widescreen touchscreen integrates ambient temperature, real-time tension, peak tension, and equivalent tension for intuitive operation.
3.Dual-test design supports platinum plate and ring methods, usable individually or simultaneously.
4.Fully automated workflow eliminates human error: auto-detects liquid interfaces, plots tension curves, locks peak values, displays direct readings, and stops measurements autonomously.
5.Enables full-range auto-calibration with weights, distilled water, and anhydrous ethanol for coefficient fine-tuning.
6.Quiet motorized sample stage with touchscreen-adjustable speed (1–300 mm/min).
7.Quick-release bracket for platinum accessories allows easy installation and on-demand force calibration with standard weights.
8.One-touch tare function ensures stable, zero-drift measurements.
9.Automatic temperature compensation converts readings to 20°C tension values based on water/ethanol references.
10.Data acquisition software compatible with all Windows systems (WIN 7/8/10/XP).
