DEW POINT CALCULATOR
The Nardi Dew Point Calculator is a free, browser-based tool for analyzing moisture content in compressed air systems. Designed for technicians, dealers, engineers, and end users working with high-pressure breathing air and industrial compressors, it converts pressure dew point measurements into a full set of humidity parameters instantly.
Three inputs drive the calculation:
Relative pressure (bar or psi) — the working pressure at which the dew point was measured
Pressure dew point (°C or °F) — the dew point reading from your moisture analyzer or sensor
Gas temperature (°C or °F) — the actual gas temperature, used to calculate relative humidity
The calculator outputs a complete moisture profile, including:
Atmospheric dew point
Partial pressure of water vapor (H₂O)
Concentration in ppm(v) and ppm(w)
Absolute humidity (g/m³)
Relative humidity (%)
Interactive pressure-dew point curve: a draggable chart plots dew point against pressure across the operating range, letting you visualize how dew point shifts as system pressure changes. Double-click to reset the view.
No login or download required. Works on all platforms: mobile, tablet, laptop, and desktop.
UNIT CONVERTER
The Nardi Unit Converter is a free, browser-based reference tool designed for compressor technicians, dealers, and end users working across metric and imperial measurement systems. Convert common compressed air and pressure-related values instantly. No registration or download required. Works on all platforms: mobile, tablet, laptop, and desktop.
