Nternal Angle Calibrator HYBD-2

Product Introduction

The internal angle calibration of gyratory compactors has always been a critical issue. Through comparative testing, it has been found that the internal angle is one of the main factors affecting the compaction performance of gyratory compactors. At present, the measurement of gyratory compactor internal angle is still considered a challenging task, resulting in significant variations in measurement results among different brands of equipment, even for the same sample.

The HYBD-2 can perform calibration and measurement of the internal angle of gyratory compactors from different manufacturers.

Standard

JTG 087-2024

Product Features

• Suitable for accurate measurement and calibration of the internal angle of gyratory compactors, and can also be used for calibration of frame stability parameters required by standards.

• Quickly and accurately measures the internal angle of gyratory compactors; the measurement can be completed within 30 seconds.

• No asphalt mixture is required. Before measurement, simply place the internal angle calibrator into the mold. The calibrator can simulate the shear force generated during the compaction process.

• Provides convenient angle adjustment and rapid calibration.

• Displays detailed angle data for each revolution with waveform visualization.

• Enables real-time observation of gyration speed variation.

• Automatically powers off after 5 minutes without operation, extending battery life.

• Battery powered and rechargeable.
