SYD-0620A tester determines the dynamic (absolute) viscosity of bitumen at 60°C by the vacuum capillary method with a constant temperature bath.
Overview
This instrument determines the absolute (dynamic) viscosity of viscous petroleum bitumen at a specified temperature (usually 60C) and vacuum (300mmHg, approx. 40kPa) by the vacuum capillary method. AI-type (or CM / MK) capillary viscometers are immersed in a constant-temperature bath; a constant vacuum is applied and the time for the bitumen to flow between graduation marks is measured and converted to dynamic viscosity, used to evaluate the high-temperature resistance and pavement performance of bitumen. The unit comprises a constant-temperature bath, vacuum system, U-tube mercury manometer and automatic timing/digital control, accommodating four capillary viscometers simultaneously, with automatic timing, data storage and printing.
Applications
• Hot mix asphalt (HMA) laboratory mix design and quality control
• Asphalt plant production monitoring and batch certification
• Road construction acceptance testing and pavement performance assessment
• Research institutions and highway engineering laboratories
Features
• Built-in thermal printer for immediate test record output
• Robust construction suitable for both laboratory and field use
• Compliant with relevant Chinese and international testing standards
• Complete with calibration certificate and operation manual

FAQ
Q1: What standards does the SYD-0620A Bitumen Dynamic Viscosity Tester (Vacuum Capillary) comply with?
A1: The SYD-0620A Bitumen Dynamic Viscosity Tester (Vacuum Capillary) is designed and manufactured in accordance with relevant Chinese national (GB) and transport industry (JTG) standards, as well as applicable ASTM and AASHTO international standards. A calibration certificate traceable to national standards is provided with each unit.
Q2: How often should the SYD-0620A Bitumen Dynamic Viscosity Tester (Vacuum Capillary) be calibrated?
A2: We recommend annual calibration by authorized technicians or by iRoad after-sales service center. For high-frequency laboratory use, semi-annual calibration is advised. The instrument is supplied with a factory calibration certificate.
Q3: What is the lead time and do you provide training?
A3: Standard units are usually shipped within 7-15 working days. Custom configurations may require 20-30 days. iRoad provides on-site installation, commissioning and operator training for major equipment; remote video guidance is available for standard laboratory instruments.
