This lithium battery electric torque wrench was independently developed and manufactured by SMG. It is used for bolting in a variety of industrial and mining applications. Through the dual controls of the sensor and digital adjustment of the single-chip microcomputer the accurate torque output of ± 2% and its output form(torque or torque + angle ) can be implemented. The high quality motor is installed to ensure surging power.

Multi-stage planetary reducers made of ultra-high strength (2140MPA) steel are used in our tools making small size and light weight. This tool is applied for the industries of oil natural gas metallurgy petrochemical aviation military railway electric power high-end assembly and others.
