Feature
+The PD23 are for medium pressure use. A preliminary pump and fine adjustment pump are incorporated so you can make pressure adjustments easily.
+Since there are two gauge ports, pressure measurements can be performed efficiently.
+Pressure can also be measured by installing a standard pressure gauge to one of the gauge ports instead of a dead-weight.
+The pressure gauge can be easily mounted to and dismounted from the mounting base with the quick fastening joint.
