Produktbeschreibung

Stainless Steel Build - This CO2 regulator is crafted from 304 stainless steel, providing excellent rustproof properties and extended service life that lasts 5x longer than plastic valves in humid aquarium environments. Accurate Flow Control - Micro-metering needle valve delivers 0.01ml/min CO2 adjustment accuracy, avoiding plant burn or fish stress while maintaining ideal 20-30ppm dissolved CO2 levels in planted aquariums. Versatile Compatibility - Choose from 4 configurations (single/dual valve with/without bubble counter) to fit CO2 systems from 5L to 500L aquariums, hydroponics, or marine setups with pressurized cylinders. Easy Installation - Ergonomically designed threads and 6mm/8mm hose adapters install in 90 seconds without tools, featuring a polished metal exterior that stops gas leaks at up to 3000psi pressure. Clear Bubble Monitoring - Integrated bubble counter (03#/04# versions) allows real-time CO2 flow rate verification, with non-reactive acrylic tube that won't fog like standard plastic counters.
