Multi-functional tester with a clear LCD display that supports three unit displays: lb, kg, and N. One-click switching provides a convenient user experience. - Easy operation: one-key automatic zeroing for simple setup, fast measurement, and reliable readings. The device uses a high-definition LCD screen for clear visibility, and a comfortable grip for ease of use during measurement. - High precision and versatility: delivers high precision and resolution in force measurement, making it a practical tool for quality control in automotive, chemical, and construction hardware industries. - Peak value and continuous load options: the knob-controlled tension meter switches between peak load testing and continuous load testing to match different experimental needs. Typical use scenarios - Automotive components: measure tension or pull force on cables, fasteners, or assemblies to verify strength and adherence to specifications during production and inspection. - Chemical packaging and lab testing: assess the pull strength of seals, closures, or connectors to ensure packaging integrity and safe handling. - Construction hardware QA: check fastening strength and material performance of bolts, screws, and related hardware to ensure reliability in finished products.
