Resonance-frequency tester for dynamic elastic modulus of concrete, stone, brick, glass, plastics and metals, e.g. in freeze-thaw tests.
Overview
It is used by universities, research institutes and testing units, as well as metallurgy, construction, bridge and hydropower industries to measure the dynamic elastic modulus of concrete, carbon, stone slabs, glass, brick, plastic and metals. Manual sweep reaches 1Hz sensitivity with jump frequency from 100Hz to 20kHz; internal memory stores 100 test results; Chinese LCD shows sweep frequency, resonance peak and signal strength; imported rotary switch for one-key operation; thermal printer and metal probes.
Applications
• Road and highway engineering laboratory testing
• Construction material quality control and acceptance
• Research and teaching laboratories
• Third-party inspection and certification bodies
Features
• Large LCD display showing real-time test parameters and results
• 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 Dynamic Elastic Modulus Tester comply with?
A1: The Dynamic Elastic Modulus 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 Dynamic Elastic Modulus 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.
