The MH-3 flowmeter is calibrated for use with the Oxymizer™ cannula for flight up to 18,000 ft. The MH-4 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 face mask up to 30,000 ft.
Both are available in either thermo plastic or plated brass CPC-type male fittings.
The thermo plastic fitting comes with 1 meter of PVC vinyl tubing and is standard equipment on all XCP systems. (Use only with OUR XCP systems, not recommended for use with factory built-in systems.)
The brass-plated metal fitting comes with 1 meter of poly tubing (Tygon® type) and is used where higher system outlet pressures are encountered, such as aircraft with built-in systems.
