Wika Capsule Pressure Gauge Model 612.20.100, 0...100 mbar / 0...1000 mmWC, Dual Scale, 4" Dial, 1/2" NPT Lower Mount, 84272198
Technical overview
This version of the WIKA 612.20.100 capsule pressure gauge is for very low pressure measurement from 0…100 mbar / 0...1000 mmWC scale on a large 100 mm dial. The copper alloy capsule measuring system is ideally suited for small over-pressures of dry, non-aggressive gases, converting the applied pressure into a proportional movement transmitted to the pointer. A stainless steel case with bayonet (cam-ring) bezel and flat instrument glass provides a durable housing for industrial and HVAC environments. The instrument follows EN 837-3 design requirements for capsule gauges and offers class 1.6 accuracy, with typical ambient temperatures from -20…+60 °C and medium temperatures up to +100 °C. With a 1/2" NPT lower Mount connection, this gauge is ideal for draft measurement, filter and blower monitoring and level indication applications where fine low-pressure resolution in mbar/mmWC is needed.
