The MESA Series 800 demand flow calibration gas regulator is designed for use with instruments that utilize a sample pump to draw the calibration gas. This saves precious calibration gas, as gas is only pulled by the pump, at the exact amount needed by the instrument. The brass regulators are recommended for non-corrosive calibration gas service. For reactive calibration gas standards, use the 800 Series regulator in stainless steel. The MESA 800 Series regulator is simple to use and makes calibration quick and easy. With no valves to turn, simply start the instrument and the 800 Series regulator does the rest.
