Wika Capsule Pressure Gauge Model 612.20.100, 0...300 mbar / 0...3000 mmWC, Dual Scale, 4" Dial, 1/2" NPT Lower Mount, 84272196
Technical overview
The WIKA 612.20.100 capsule pressure gauge provides accurate measurement of low pressures from 0…300 mbar / 0...3000 mmWC using a copper alloy capsule measuring system. A 100 mm dial with 0…300 mbar primary scale and red mmWC secondary scale allows easy reading of pressure in mbar and water column units. The instrument is built with a stainless steel case and cam-ring (bayonet) bezel, flat instrument glass window and 1/2" NPT lower Mount process connection, offering a rugged housing for industrial, HVAC and environmental applications. Design and performance are based on EN 837-3 with class 1.6 accuracy and typical permissible ambient temperatures from -20…+60 °C. This configuration is well suited for low-pressure pneumatic systems, filter monitoring and level indication where medium pressure ranges up to 300 mbar are required.
