Flowmeters, MH3 & MH4


MH4-MH3-72The MH3 has an altitude/flow scale calibrated for the unique Oxymizer oxygen-conserving cannula. The scale is marked in 2,000 ft. increments for flight levels up to 18,000 ft. To receive the proper amount of oxygen, simply adjust the MH3 to where the scale reads the same altitude you are flying. Example: If you are at 15,000 ft. you would hold the meter vertical and adjust the needle valve on the MH3 to where the ball reads between the 14 and 16 on the scale. Counter clock-wise increases and clock-wise decreases oxygen flow. The outlet flow of the MH3 can be adjusted well beyond the limits of the scale for emergency purposes.
