Standard force output
Standard force weights and a standard force arm generate static torque across a 0.625 to 5,000 N·m output range.
CRITERO Torque Calibration Equipment
GJJ Series Standard Static Torque Calibration Device
Small & Medium Range Solution (0.625 - 5,000 N·m)
The GJJ series calibration device uses standard force weights and a standard force arm to generate standard static torque. Through center-axis output, it enables high-precision calibration of torque meters and torque sensors.
Product Overview
A standard static torque generation solution for small and medium range calibration
The GJJ Series Standard Static Torque Calibration Device uses weights, a force arm and balancing adjustment structure to establish stable standard torque output for laboratories, metrology organizations and production inspection environments.
High-precision calibration
System accuracy reaches 0.03%, meeting high-precision calibration requirements for torque meters, torque sensors and related metrology equipment.
