Why choose our vacuum sealer?

✅Core strengths

• Complies with the new regulationsDeveloped strictly in accordance with the JTG3410-2025 standard, with standardized testing procedures to assist laboratories in easily passing evaluations and certifications.

• Accurate 'zero water leakage' sealingAutomatic vacuum pumping ensures a tight fit between the specimen and the sealed bag, followed by automatic heat sealing to isolate moisture infiltration and ensure the accuracy of measurements of bulk density, relative bulk density, and connectivity porosity.

• One click intelligent operationAutomated vacuum pumping, pressure holding, and sealing process to reduce human error and improve detection efficiency and consistency.

• High precision pressure control: Pressure range0~-0.1MPaStable and controllable, meeting the strict requirements of the standard for sealing negative pressure.

• Reasonable spatial design: Studio size380×200×300mmApplicable to common specimen sizes; The whole machine has a compact structure and flexible placement.

✅Applicable subjects

• Various types of high water absorbing and open graded asphalt mixturesSuch as SMA, OGFC, porous asphalt mixtures, etc.

• Test scope：

  1. Measure the relative bulk density and bulk density of the specimen;

  2. Calculate key volume indicators such as porosity and mineral material porosity;

  3. Optional measurement of connectivity porosity (in accordance with standard procedures).

✅Strictly control environmental conditions

Strictly maintain the temperature in the experimental environment25℃±0.5℃Ensure comparability and reproducibility of data across different laboratories.
