Photoelectric cone penetration tester for liquid limit, plastic limit and plasticity index of fine-grained soils.
Overview
This instrument is suitable for determining the liquid limit, plastic limit and plasticity index of fine-grained soil. It is a common equipment for geotechnical testing, subgrade filler classification and engineering geological parameter determination. Adopting the photoelectric detection principle, the instrument calculates the liquid limit and plastic limit of soil by measuring the cone penetration depth combined with water content test results. It consists of a main unit, measuring head, lifting mechanism, control system and display device, featuring accurate measurement, intuitive operation and stable performance.
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
• 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 Photoelectric Liquid and Plastic Limit Tester comply with?
A1: The Photoelectric Liquid and Plastic Limit 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 Photoelectric Liquid and Plastic Limit 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.
