Electromagnetic non-nuclear density gauge for fast, radiation-free density measurement of asphalt pavement, base and subgrade.
Overview
The non-nuclear density gauge (referred to as non-nuclear gauge) is a non-destructive testing instrument used for rapid measurement of the density of subgrade, pavement and base course materials. Based on the electromagnetic method, it reflects the compaction state of materials by detecting the dielectric constant, without damaging the materials and without requiring a radioactive source, making it safe and convenient to use. It is widely used in quality inspection during the construction of highways, urban roads, airports, ports, railways and other engineering projects, especially for on-site density testing of asphalt pavements, base courses, subgrade fills and other materials. The instrument features fast testing speed, simple operation, stable data and accurate results, which can effectively improve construction inspection efficiency and provide a reliable basis for construction quality control.

FAQ
Q1: What standards does the Non-nuclear Density Gauge comply with?
A1: The Non-nuclear Density Gauge 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 Non-nuclear Density Gauge 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.
