Product Description

MATHESON made in the USA

 

 

High-purity regulators designed for analytical applications using non-corrosive or semi-corrosive gases.

Applications

• Supply of carrier gas/detector support gas for a variety of gas chromatography applications (see table below for details).
• Supply of calibration standards to on-line process analyzers, emission monitoring systems, etc.
• Supply of high-purity non-corrosive or semi-corrosive gases to applications requiring constant delivery pressure.

MATHESON strongly recommends the use of a cross-purge with any regulator put into highly corrosive or toxic gas service. You can easily add a cross-purge to this model regulator by selecting "Yes" for the Cross Purge option above.

Looking for something a little bit different? Different inlet or outlet fitting or remove the outlet valve? Check out our Modified 3810A Pressure Regulator.
