Particle charge tester that identifies whether emulsified asphalt is cationic or anionic, with electrode assembly and digital timer.
Overview
The Emulsified Asphalt Particle Charge Tester is suitable for determining the ionic charge of emulsified asphalt particles and judging whether the emulsified asphalt is cationic or anionic. The instrument consists of a main unit, a transparent test cylinder, electrode assembly, a digital timing module and a control system. It can automatically control the test time and stop automatically after the test. It is easy to operate and suitable for emulsified asphalt performance testing in highway engineering.

FAQ
Q1: What standards does the Emulsified Asphalt Particle Charge Tester comply with?
A1: The Emulsified Asphalt Particle Charge Tester 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 Emulsified Asphalt Particle Charge Tester 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.
