Measured by hands is not stable.
What if the quantity above thousands of meters? Are you going to measure them meter by meter?
The advanced equipment solves this problem, every batch of production process will be record and log in the system, if there's any tolerance above or blew the setting data, it will alarm and record in the logbook.
SRT's production line is dimensioned by infrared.
This advantage is that the size of the entire production line can be monitored without omission.
Every meter of pipe extruded from the machine is measured.
Unlike hand inspection, inspection, and spot inspection. The tube size accuracy of the SRT Hose is 99.9%.
