Overview
The WIKA 611.10 is a capsule-element low-pressure gauge engineered for sensitive, accurate measurement in controlled environments. This 0-3 PSI model features ±1.6% full-scale accuracy and is ideal for laboratory, medical, environmental, and pneumatic system monitoring. With a copper alloy process element and NEMA 2-rated steel case, it delivers reliable performance for gaseous, dry, and non-aggressive media.
Key Features
- Capsule pressure element — exceptionally sensitive to low-pressure differentials
- Class 1.6 accuracy (±1.6% of full scale) per EN 837-3 design standard
- Copper alloy wetted parts — corrosion-resistant for long service life
- Front-face zero adjustment — field-calibration without opening the case
- NEMA 2 steel case with clear plastic window — protected against light moisture and industrial dust
- 2.5″ dial with black lettering and aluminum pointer — easy-to-read analog display
