Overview
The Wika 0-100 InH2O pressure gauge is a precision instrument designed for low-pressure measurement applications. Built with brass wetted parts, this gauge delivers consistent and reliable readings across the full range of 0–100 inches of water column (InH2O). It meets industry accuracy standards and is widely used in HVAC, process control, and monitoring applications where precise low-pressure data is critical for system performance and safety.
Key Features
- Brass wetted parts resist corrosion and ensure long service life in low-pressure environments
- Measuring range: 0–100 InH2O (inches of water column)
- Suitable for gaseous and liquid media in non-aggressive applications
- Complies with ASME B40.100 accuracy standards
- Compact dial design for easy readability in tight installations
- Cost-effective replacement for legacy gauge systems
