Bourdon Tube Pressure Gauge, Copper Alloy - 113.13

Brand: WIKA Instruments Ltd.
The hydraulic pressure gauge model 113.13 is a liquid-filled mechanical pressure gauge with plastic case.

The liquid filling causes damping of the internal components and contributes to an increased vibration resistance and shock resistance.
Features
  • Vibration and shock resistant. 
  • Design per EN 837-1. 
  • Scale ranges up to 0 ... 400 bar.
