Prisma Electronics AirPro Densimeter Air Temperature, Pressure & Density Gauge

    The Prisma Electronics AirPro Densimeter provides precise measurements of air temperature, pressure, density, relative humidity, and altitude, enabling accurate fuelling adjustments to maximise engine performance. Designed specifically for two-stroke and four-stroke engines, it records session data and connects wirelessly via the Prisma Electronics app, allowing you to analyse and fine-tune your carburetion settings based on real-time environmental conditions.

    Here’s what makes the AirPro Densimeter an essential tool for race engine tuning:

    • Comprehensive air measurement: Accurately tracks temperature, pressure, density, relative humidity, and altitude to provide critical environmental data for optimising engine performance.
    • Real-time and logged data storage: Stores up to 50 sessions on the device, allowing you to review and refine fuelling adjustments based on previous conditions.
    • Wireless app integration: Seamlessly connects to the Prisma Electronics app, enabling remote access to session data, environmental logs, and carburetion adjustments.
    • Track-linked session data: Logs all readings with location-based tracking, ensuring you can analyse air quality at specific circuits and adapt fuelling accordingly.
    • Detailed session notes and exports: Add tuning notes for each session and export data as PDF or Excel files for in-depth performance analysis and team collaboration.
    • Critical air density insights: Displays precise air density values, helping you determine the correct air-fuel ratio for maximum combustion efficiency.
    • Precision carburetion tuning: Eliminates guesswork by providing accurate data to refine carburettor settings, improving throttle response and power delivery.

    Engines running on carburettors, especially high-performance two-strokes, demand precise fuelling adjustments to deliver maximum power. Air temperature, pressure, and density fluctuate with changing weather and altitude, directly impacting the air-fuel ratio. The AirPro Densimeter removes uncertainty by providing real-time environmental data, allowing you to fine-tune jetting and mixture settings for optimal combustion. Storing and reviewing session data ensures consistent performance across different track conditions, helping you maintain peak engine efficiency throughout race day.

    Accurate air measurement is essential for achieving the best possible engine performance. The AirPro Densimeter gives you the data needed to adjust fuelling with confidence, ensuring your race engine operates at its full potential in any environment.

    Supplied with a storage case. A protective silicone cover is also available separately.
