MH3 or MH4 Flowmeter with BNC Connector and Tubing
Flowmeters for Built-in systems with tubing and connectors.

Designed for OEM Built-In systems, the MH-3 Flowmeter (green) is calibrated for use with the Oxymizer™ cannula for flight up to 18,000 ft. The MH-4 (red) has two altitude flow scales. The left (compressed) scale is calibrated for the Oxymizer™ cannula and is limited to flight of 18,000 ft.and below. The right scale is calibrated for a standard cannula or facemask up to 30,000 ft.

These Flowmeters come with 1 meter of Poly Tubing (Tygon® type) and Brass plated metal fittings. They are used where higher system outlet pressures are encountered, such as aircraft with built in systems.
