Brand New Argon / CO2 regulator and fl-ow meter.Measuring range: 0-25MPa. A regulator that converts a high pressure gases into a low pressure gases and keeps the pressure and f-low of the output gases constant. Poly-carbonate fl-owtube and outer cover are impact resistant for maximum durability. Flowmeter is back pressure compensated to ensure accurate readings when line restrictions are present. Perfect for enhancing the amount of available carbon dioxide and accelerating plant growth rates and yields by up to 40% in indoor hydroponics, grow rooms, grow tents and warm houses. A regulator that converts a high pressure gases into a low pressure gases and keeps the pressure and f-low of the output gases constant. Features: Easy reading pressure gauge. Poly-carbonate flowtube and outer cover are impact resistant for maximum durability. Flowmeter is back pressure compensated to ensure accurate readings when line restrictions are present. Refined from fine quality materials, compact structure with fine sealing. Perfect alloy body, stable voltage regulation, firm and reliable. Large handle switch, anti-slip design, more labor-saving.
