SUNDOO Dynamic Torque Meter ST-R

The ST-R Dynamic Torque Meter Series (1–500 N·m) delivers accurate dynamic torque measurement up to 1000 rpm, featuring peak hold, GO/NG comparison, unit conversion, built-in printing, and RS-232C data output. Ideal for motor and rotating machinery torque calibration.

  • Wide Dynamic Torque Range: Models ST-1R to ST-500R (1–500 N·m).
  • Dynamic Testing Capability: Supports rotational speeds up to 1000 rpm.
  • Precision Resolution: From 0.0005 N·m to 0.2 N·m, depending on model.
  • Accuracy: Within ±1% to ±2%, depending on capacity range.

Description

The ST-R Dynamic Torque Meter Series is a high-performance instrument specifically designed for dynamic torque measurement. It is particularly suitable for calibrating and verifying the output torque of electric motors, power tools, and rotating machinery, making it widely used in electrical machinery manufacturing, mechanical engineering, and scientific research institutions.

Covering a broad capacity range from 1 N·m to 500 N·m, the ST-R Series provides reliable torque analysis under rotational conditions with a maximum speed of 1000 rpm. With load resolutions from 0.0005 N·m to 0.2 N·m, depending on the model, the system ensures precise and stable measurement performance.

The instrument is equipped with intelligent digital functions to enhance testing efficiency. The peak holding and auto-release function (1–10 seconds adjustable) captures maximum torque values, while the GO/NG tolerance comparison function offers instant pass/fail judgment via green/red indicator lights. The system can store 10 sets of data and calculate the average, improving testing consistency and quality control.
