Capsule Pressure Gauge, Copper Alloy or Stainless Steel - 614.11, 634.11

Brand: WIKA Alexander Wiegand SE & Co. KG

The model 614.11 and 634.11 capsule pressure gauges are based upon the proven capsule measuring system. The capsule measuring principle is particularly suitable for low pressures.

On pressurization, the expansion of the capsule element, proportional to the incident pressure, is transmitted to the movement and indicated.
Features
  • Low scale ranges from 0 ... 2.5 mbar.
  • Panel mounting.
  • Zero point setting in front.
