ZBL-C310A half-cell potential detector that measures the corrosion state and distribution of steel reinforcement in concrete.
Overview
The ZBL-C310A ZBL-C310A Rebar Corrosion Detector measures the corrosion degree and distribution of steel bars inside concrete. Reinforcement corrosion reduces the effective cross-section and increases volume, causing concrete expansion, spalling and reduced bond and load capacity, directly affecting structural safety and durability. The instrument provides two methods: electrochemical measurement (natural potential method) and gradient method, with corrosion voltage accuracy of 0.1mV. Corrosion degree is displayed in 9-level grayscale or color graphics corresponding to the potential range; equipotential contour maps can be drawn (contour difference 1100mV settable). It supports single-electrode and double-electrode modes, enabling early detection before corrosion causes major accidents.
Applications
• Road and highway engineering laboratory testing

Features
• High measurement accuracy with stable repeatability
• Large LCD display showing real-time test parameters and results
• 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 ZBL-C310A Rebar Corrosion Detector comply with?
A1: The ZBL-C310A Rebar Corrosion Detector 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 ZBL-C310A Rebar Corrosion Detector 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.
