Precision Torque Balance

The precision torsion balance measures minute masses or torques by utilizing the angular displacement generated when an elastic element is subjected to torsion. It relies on the linear relationship between the torsion angle of the hairspring and the torque, with the pointer directly indicating the numerical value. It is used in laboratories for weighing trace samples, detecting material friction coefficients, and calibrating devices for small force values.
Selection
When selecting, consider the range to match the sample weight, and ensure the division value meets the weighing accuracy requirements. Pay attention to the impact of environmental vibrations and air currents, and equip with a windbreak cover. Check the corrosion resistance of the balance material, and opt for an easy-to-clean design for convenient maintenance. Confirm the traceability of the calibration weights and ensure the operation interface aligns with user habits.
