CO2 Analyzer

The OxyGuard CO2 Portable is a reliable and easy to use instrument that measures the free dissolved carbon dioxide concentration directly in the water. The CO2 concentration is shown on the display, and there is an analogue output. A version with built-in data logger is available.

The OxyGuard CO2 measures the free dissolved CO2 directly and is not affected by carbonates or other dissolved substances. It is the free dissolved CO2 – in other words the CO2 gas partial pressure – that affects the fish. The OxyGuard CO2 thus gives simple, continuous and direct measurements of the amount of carbon dioxide in the water that will affect the fish.

The analyser is easy to calibrate using the front panel “slope” and “zero” adjustments – after which you just put the probe in the water and measure. There is a salinity adjustment. Calibration intervals are long, and the OxyGuard CO2 does NOT need regular maintenance.
