Portable Dissolved C02 Analyser Direct Measurement Dissolved Carbon Dioxide The OxyGuard C02 Portable is a reliable and easy to use instrument that measures the free dissolved carbon dioxide concentration directly in the water. The CO2concentration is shown on the display, and there is an analogue output. A version with built-in data logger is available. The OxyGuard C02 measures the free dissolved C02 directly and is not affected by carbonates or other dissolved substances. It is the free dissolved C02 - in other words the C02 gas partial pressure - that affects the fish. The OxyGuard C02 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 C02 does NOT need regular maintenance.

The OxyGuard CO2 Portable Dissolved CO2 Analyser consists of a probe and a battery powered transmitter. The latter has a display and an analogue signal as output. The probe is, as standard, delivered with a 3 m cable. The transmitter has an on/off switch, "slope" and "zero" adjustments. A battery charger and calibration accessories, i.e. calibration beaker with stirrer, calibration fluid, calibration conditioner and dosing syringe are included. The probe measures the carbon dioxide content of the water directly by detecting the carbon dioxide partial pressure in the water. It is important to...
