The nature of the gauge design and the material used results in a phenomenal operating accuracy over an entire range of 0 to 15,000 psi. Other features which distinguishes CIRCOR Aerospace gauges are the following:
Quality 
Each gauge is designed, assembled, and adjusted to meet the customer's specifications under rigid quality control standards

Dependability
The Helical bourdon coil is the only moving part, which greatly reduces the possibility of component failure.

Accuracy
Normally in the ±2-4% range. Greater accuracy possible.

Maintenance Free
The gauge is designed to operate accurately without periodic adjustment or other normal maintenance.

Shock-/Vibration-proof
Design construction (no linkages, gears, return springs) improves the ability of the gauge to withstand vibration and shock over extended periods of usage.
