AirPro Densimeter for Optimizing Combustion in Two-Stroke and Four-Stroke Engines Specifically designed for two-stroke and four-stroke engines, the AirPro Densimeter measures key parameters such as Temperature Pressure Relative Humidity Altitude Air Density It store session data, allowing you to optimize carburetion adjustments according to environmental conditions, enabling optimal carburetion adjustments based on environmental conditions, ultimately improving engine performance. Wireless connection of the instruments through the Prisma Electronics APP to view and export all stored sessions. What Parameters are displayed? Date & Time Air Temperature - Celsius of Fahrenheit Barometric Pressure hPa Relative altitude mt / ft Relative Humidity % Air Density - Kg/m3 - lb/ft3 Relative altitude mt / ft Relative Humidity % Air Density - Kg/m3 - lb/ft3 What does air density indicate? In technical terms, air density represents the amount of air mass present per unit of volume in a given environment. It is influenced by three main factors: Atmospheric Pressure: Higher atmospheric pressure compresses air molecules, increase density. Air Temperature: Higher Temperature expand air molecules, reducing density, while lower temperature increase it. relative Humidity: Humid air is less dens than air dry. Air Density in Motorsport Is a critical parameter because: It determines the amount of oxygen available for combustion in engines. It directly affects carburetion and the air-fuel ratio, which in turn impacts engine power.
