Product Description

MATHESON made in the USA

 

 

Matheson’s Model 7400 four-tube mixer are used for mixing four gas streams and utilize our FM-1050 150 mm flow tubes. The four-tube mixer does not come with a mixing tube. All tubes are supplied with a single glass float.

The tubes are backpressure compensated by mounting the control valve on the outlet of the tube. A highly sensitive pressure regulator is recommended for each of the inlet gas streams to avoid fluctuations in gas flow which could cause inaccuracies in mixing concentration.

It is suggested that pressure of the gas supplied to the mixer be 20 psig or 50 psig as reference charts are available for most gases at those pressure ranges.

Standard with this series is the uniquely designed Tube-Cube®. The “cube,” a unitized tube holder, aligns the tube quickly and easily for simple tube installation or replacement. The Tube-Cube® provides protection during handling, reducing chipped tube ends, broken tubes and misalignment. The 1.5 X scale magnification lens allows for a more accurate reading. End seals in the FM-1050 are direct acting and non-rotating for fast alignment and convenient service access.

Valve Options
• Utility (six-turn) valve for those who desire control as well as indication
• High accuracy (fifteen-turn) valve, for very precise control and repeatability
