Model 716.05 Differential Pressure Gauge

Brand: WIKA Instruments Ltd.
The compact differential pressure gauge, model 716.05 with a nominal size of 80 mm, has been specifically designed for measuring points at which differential pressure measurements with low differential pressures take place. 

In addition, an overload safety of up to 16 bar is guaranteed, on either side.
Features
  • Differential pressure measuring ranges from 0 … 16 mbar.
  • High working pressure (static pressure) and high overpressure safety up to 16 bar.
  • Numerous options for installation, connection form and connection location.
