Wika Capsule Pressure Gauge Model 612.20.100, 0...60 mbar / 0...600 mmWC, Dual Scale, 4" Dial, 1/2" NPT Lower Mount, 84272199
Technical overview
WIKA 612.20.100 capsule pressure gauge specially for very low-pressure measurement from 0…60 mbar / 0...600 mmWC. The copper alloy capsule element is particularly sensitive in this range and is suitable for dry, non-aggressive gases. The 100 mm dial shows a 0…60 mbar primary scale with red mmWC secondary scale, giving excellent resolution for fine draft and low-pressure readings. A stainless steel case with bayonet (cam-ring) bezel and flat instrument glass protects the movement and capsule, while the 1/2" NPT lower Mount process connection enables straightforward installation on manifolds, ducts or impulse lines. In line with EN 837-3, the gauge achieves class 1.6 accuracy and typical ambient and medium temperature ranges of -20…+60 °C and up to +100 °C respectively. This configuration is ideal for sensitive draft measurement, filter and blower supervision and level indication at very low pressures.
