Description
The STM-20 Torque Tester is a precision digital dynamic torque tester designed to measure and calibrate torque for motors, reducers, and other rotating machinery. It is capable of performing both dynamic and static torque testing, making it suitable for industrial, manufacturing, and scientific research applications.
Equipped with a high-accuracy sensor, the STM-20 provides a resolution of 0.01 N·m and measurement accuracy within ±1% FS. Its φ30 mm connecting shaft accommodates standard couplings for smooth torque transmission, and the system supports rotational speeds up to 1000 rpm. The intelligent digital interface ensures reliable readings and repeatable results for torque verification and calibration tasks.
With a robust structure and compact footprint, the STM-20 is ideal for motor testing, machine calibration, and research laboratories that require precise and controlled torque measurement.
