UMA 5-300-41 is a 3⅛ in (79 mm) non-sensitive altimeter with a 0–10,000 ft range and a barometric setting window in millibars (hPa). The single pointer has markings every 100 ft. The instrument weighs 10.6 oz (about 300 g), and the case is Valox 420 plastic.
The 3⅛ in case is not sealed, so UMA states that this altimeter must not be connected to the static line; a static leak would result. The center port stays unconnected, and UMA requires no connection except in a pressurized cabin or an open cockpit with moving air behind the panel. The knob sets the window to the barometric pressure of the nearest airport; the reading should then match field elevation within ±100 ft. The bezel is 3.25 in square with three mounting holes on a 3.5 in bolt circle, and the instrument is 3.34 in long including the knob. UMA lists the other millibar versions as 5-300-40 (0–5,500 ft), 5-300-42 (0–20,000 ft) and 5-300-50 (0–3,000 m).
UMA lists the 5-300-41 in its non-TSO range of flight instruments for experimental aircraft; the instrument has no TSO authorization. UMA publishes a panel cut-out drawing for the 3⅛ in altimeter. Fit depends on the aircraft type.
