making this one of themost accurate regulators available from full cylinder toempty

Color: Yellow

Note: A Cross-Purge Assembly must be used in conjunction with these models in order to ensure effective purging of hazardous gas traces during cylinder change out

These regulators are typically used in conjunction with other high-pressure regulators or on house-line systems that limit inlet pressure to 250 psig (except on model N570K the inlet pressure limit is 10 psig)

two-stage analytical series and high-purity stainless steel regulators are ideally suited for lecture bottles and other small cylinders

The regulator has a unique design to reduce weight and make the regulator more durabe
