  • OxyGuard Polaris C CO2 Handheld Meter OxyGuard Without Calibration Kit

    OxyGuard OxyGuard Polaris C CO2

    The OxyGuard Polaris C 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. The OxyGuard Polaris C 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 Polaris C 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.

  • OxyGuard Handy Polaris C TGP Total Gas Meter Handheld Meter OxyGuard

    OxyGuard OxyGuard Handy Polaris C TGP Total Gas Meter

    The OxyGuard Polaris C TGP (Total Gas Pressure) is a hand-held gas pressure meter. It can operate in three modes, one where it acts as a standard Handy Polaris dissolved oxygen (DO) meter, one where it is a total gas pressure meter that shows pressures as percent saturation values and one where it is a total gas pressure meter that shows pressures as volume percentages. The user can choose which value is shown in large figures in the display. This can, for example, be the percent saturation value for gases other than oxygen. The instrument incorporates a data logger. Messages on the display, and menu functions, make the Polaris C TGP easy to use.
