Interchangeable with steel, refillable CO2 cannisters, Swell has a range of pressure gauges to ensure you can monitor the pressure of CO2 into the aquarium and monitor the cylinder pressure.
Quality products designed with accuracy and performance in mind, Aqua Medic's Regulating Pressure Gauge is a necessary piece of kit. With two pressure instruments you can study levels of cylinder and working pressure. The JBL Pro Flora m001 pressure gauge can be used with both refillable and disposable cannisters. Again with two gauges, you can safely monitor levels for accurate results.
