General description When the inlet pressure and outlet flow change, this CO2 pressure reducer maintains a stable outlet pressure. It is designed for use with hyperbaric oxygen in cylinders and acetylene gas, utilizing a decompression device to reduce pressure effectively. This double tube bubble counter flow meter is ideal for welders, helping to reduce costs during the welding process. Technical specifications Material: Metal Color: Gold Measurement allowed error: +/- 1-3 cm Other information Content: 1 x Mig Tig CO2 Flow Meter Note: Light irradiation and different displays may cause the color of the item to be slightly different from the real thing.
