Purpose:
Used to measure the twist of various cotton, wool, silk, hemp, chemical fiber and other yarns
Characteristic:
Features: man-machine conversation is adopted, and the final results are displayed, and LCD display is used to simplify the operation.
It is convenient to adjust the zero position and has the function of data saving. Single chip microcomputer control is adopted to ensure the action.
Control part: use high-power triode to avoid interference caused by relay closing, and enhance the stability of the machine.
During operation, test data can be queried at any time.
