Simple demand flow regulator to bring the gas flow rate from tank pressure to on demand flow.
This new single stage design using balanced valve stem technology is more sensitive than older two stage technologies providing g better performance even with high inlet pressures. This regulator is designed for use with instruments that use a pump to draw the calibration gas into the instrument. The 3950 series demand flow regulator provides the exact amount of calibration gas the instrument pump requires. This simple to use regulator makes calibration quick and easy by eliminating the need for sample bags, flowmeters, or special operator training.
