Laser plummet with visible semiconductor laser beam for vertical alignment in high-rise buildings, towers, shafts and bridge piers.
Overview
Based on optical collimation, this instrument uses a semiconductor laser to produce a visible beam coincident with the telescope line of sight, directly observable by the eye. Its integrated body is stable and reliable. The semiconductor laser is small, light, shock-resistant and long-lived; the laser axis is strictly concentric, same-focus and coaxial with the telescope, producing a visible red spot on the target. The lower plummet has automatic time-delay shutoff to extend laser life and save battery; it needs no focusing, improving accuracy. A square laser target is provided, and an optional zone plate produces a red crosshair. A graduated circle supports measurement and calibration.
Applications
• Road and highway engineering laboratory testing
• Construction material quality control and acceptance
• Research and teaching laboratories
• Third-party inspection and certification bodies
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 Laser Plummet comply with?
A1: The Laser Plummet 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 Laser Plummet 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.
