Just push and you can check the pressure!




  • When you want to measure the pressure in the circuit, just push the hand wheel.
  • The pointer of the pressure gauge is normally located at the "0" (zero) position. This keeps the pressure gauge accurate for a long time, and ensures improved durability.
  • This design is best suited to check pressure measurement.
  • If you want to check pressure for a long period of time, turn the hand wheel in the clockwise direction after pushing it. Then the hand wheel is locked at the pressure test position.
