All types of pressure gauges produced by our factory have commonly used movements and patented movements: patent numbers. 2 and. 4. The application of these two patents can prolong the service life of pressure gauges
Longevity is doubled. The patented product model fluctuates from the original pressure gauge model by adding "J" after the first letter "Y" in the prototype number. As for the ordinary pressure gauge model Y100, the patented product model is YJ100, and so on for other models.
