MH4 Flowmeter with CPC Fittings for use with XCP systems

For Oxymizer Cannula or Standard Cannula or Standard Face Mask - 25,000 feet
The MH4 flowmeter can operate at flight levels above 18,000 ft. with a face mask. This will use much more oxygen (1 liter/min. per 10,000 ft.) than the MH3 and Oxymizer cannula. The MH4 has two altitude/flow scales. The left (compressed) scale is calibrated for the Oxymizer cannula and is limited to flight levels of 18,000 ft. and below. The right scale is calibrated for a standard cannula and standard face mask and is limited to 25,000 ft.. The outlet flow of the MH4 can be adjusted well beyond the limits of the indicated scale for emergency purposes.  Includes 1 meter of tubing and XCP connector.

Maximum Altitude: 25,000 feet
