FTDM laser tunnel profile detector for fast measurement of tunnel excavation profiles, linings and clearances with direct report output.
Overview
The FTDM series FTDM Laser Tunnel Profile Scanner is used for rapid measurement of tunnel excavation profiles, large-span building inner contours, slope protection/retaining walls, dam crest and trench excavation monitoring, bridge static deflection, mine clearance limits, and construction/completion acceptance and earthwork volume calculation. It offers high-speed precise measurement with direct report output (no post-processing), high-precision angular control, massive storage, compact integrated design, and an intuitive dedicated graphic controller.
Applications
• Tunnel lining crack, leakage and spalling inspection
• Highway and railway tunnel routine maintenance surveys
• Tunnel construction quality acceptance
• Urban underground space and metro tunnel assessment
Features
• High measurement accuracy with stable repeatability
• Laser measurement technology for non-contact, high-resolution detection
• 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 FTDM Laser Tunnel Profile Scanner comply with?
A1: The FTDM Laser Tunnel Profile Scanner 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 FTDM Laser Tunnel Profile Scanner 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.
