The KDJ5-AMI Safety Helmet Impact and Penetration Tester is widely used in various industries and research institutions to ensure the safety and reliability of protective headgear. Below are key application scenarios:
Construction Industry
On construction sites, this tester is essential for quality control of safety helmets used by workers. It enables on-site or laboratory-based inspection of newly procured helmets, verifying their ability to absorb impact energy and resist penetration from falling objects, thus ensuring compliance with national safety standards such as GB/T 2811-2007 and GB/T 2812-2006.
Mining and Tunneling Operations
In underground mining and tunneling environments where the risk of rock falls and sharp object impacts is high, the tester is used to evaluate the protective performance of safety helmets under extreme conditions, ensuring that head protection equipment meets rigorous safety requirements.
Power and Electrical Utilities
Utility companies use this equipment to test helmets designed for electrical work, ensuring they provide adequate impact and penetration resistance while maintaining compliance with industry-specific safety protocols.
Occupational Safety Laboratories
Governmental and third-party testing laboratories employ the KDJ5-AMI tester for certification, routine inspection, and comparative analysis of safety helmets from different manufacturers. Its high-precision sensors and automated data processing ensure reliable and repeatable test results.
Research and Development
Helmet manufacturers and material scientists use the tester during the product development phase to evaluate new materials, designs, and structural improvements. The accurate force measurement and peak value recording support innovation in lightweight, high-strength protective headgear.
Industrial Manufacturing
In factories and industrial plants, especially those with overhead operations or heavy machinery, regular testing of safety helmets ensures ongoing worker protection and adherence to occupational health and safety regulations.
Emergency Response and Rescue Services
Firefighters, rescue workers, and other emergency personnel rely on high-performance helmets. This tester helps verify that their helmets can withstand extreme mechanical stress during operations.
With its robust design, automated control system, and compliance with international testing standards, the KDJ5-AMI Safety Helmet Impact and Penetration Tester serves as a critical tool in safeguarding human life across high-risk industries.

Support
The KDJ5-AMI Safety Helmet Impact and Penetration Tester is engineered with advanced technology and user-centric design to deliver precise, reliable, and safe performance. Key features include:
Microcomputer Automatic Control System
Equipped with a dedicated processing unit for real-time dynamic signal acquisition, data analysis, and result output. Optional built-in printer for immediate test report generation.
High-Precision Dynamic Force Sensor
Utilizes a German-imported high-accuracy dynamic load cell with a measurement range of 0–20 kN and a frequency response of ≥5 kHz. Ensures force measurement accuracy down to 1 N, with automatic peak force capture and hold.
Dual-Function Testing Capability
Designed to perform both impact resistance and penetration resistance tests in one integrated system, meeting the requirements of GB/T 2812-2006.
Free-Fall Mechanism
Employs a true free-fall design without guide rails or导向 components, eliminating the need for complex velocity compensation and ensuring realistic simulation of real-world impact conditions.
Magnetic-Free Release Mechanism
Features a non-magnetic release structure that ensures smooth, consistent drop of the impact hammer and puncture cone, avoiding interference and enhancing test repeatability.
Adjustable Vertical Height Control
Precision vertical screw handle allows easy and accurate height adjustment. Drop height is set to 1000 mm ± 5 mm, clearly marked for quick verification.
Replaceable Impact and Penetration Components
Standard-Compliant Headforms
Includes both Type 1 and Type 2 magnesium-aluminum alloy headforms (5.0 kg ± 0.1 kg), manufactured to exact specifications of GB/T 2812-2006. Durable and repairable after impact, offering longer service life compared to traditional wooden forms.
Automatic Centering
The release mechanism automatically aligns the hammer and cone to the center of the safety helmet, improving test consistency.
Integrated Safety Protection
Surrounding metal safety cage with secure fastening and a foot-operated switch at the base minimize the risk of accidents during testing, ensuring operator safety.
Level Adjustment System
Built-in leveling feet ensure the tester remains perfectly horizontal, enhancing test accuracy and repeatability.
LED Digital Display
Clear real-time display of force values with 1 N resolution, automatically locking and showing the peak impact force.
Conductive Contact Detection
Integrated electrical circuit and alarm system trigger an audible or visual signal when the puncture cone makes contact with the headform, indicating failure during penetration tests.
Modern Structural Design
Constructed with European-standard aluminum alloy frame for high stability, corrosion resistance, and aesthetic appeal. Internal cable routing provides a clean, professional appearance.
User-Friendly Operation
Simple and intuitive interface allows quick setup and testing, reducing operator training time and increasing testing efficiency.
