  • CH338 Digital Torsion Meter is a specialized instrument designed for evaluating the mechanical strength of lamp caps within the lighting industry. Equipped with an intelligent microprocessor, it performs torsional strength testing on various types of lamp caps, including screw bases, bayonet bases, and fluorescent lamp pins. The CH338 supports bidirectional torque measurement and features programmable upper-limit torque alarms as well as data retention in the event of a power loss. Offering simple operation and stable, reliable measurements, the device is used to assess the structural integrity of the connection between a lamp cap and its glass bulb or plastic housing—thereby preventing safety hazards such as the detachment of the lamp cap. It is widely utilized by light source manufacturers, third-party testing laboratories, and research institutions for product reliability verification.
