Radiant Altimeter Vertical Speed Indicator Combo For 2 1/4

The Radiant Technology Altimeter + VSI Combo, manufacturer part number RI-2024-1, combines altitude and vertical-speed indication in one compact panel-mount instrument. Its sunlight-readable display presents altitude and vertical speed with both digital values and analogue-style needle representations for clear, at-a-glance reference.

• Designed for a 2¼ in (approx. 57 mm) instrument position; a left-side rectangular panel cut-out is required for full screen visibility.
• Digital and analogue-style altimeter indication, with a digital Kollsman window.
• Digital and analogue-style VSI indication; negative vertical-speed values are colour-coded red.
• User-selectable feet or metres display modes; barometric-pressure setting selectable in inHg or kPa.
• Altimeter range: 0 to 20,000 ft. VSI range: ±1,999 ft/min.
• Operating supply: 6.5 to 14 V DC, approximately 0.125 A. Reduced-brightness operation is supported down to 4.5 V.
• Dimmable through an external switch or potentiometer; black 3D-printed nylon case with chopped carbon fibre.
