The OxyGuard Polaris C TGP (Total Gas Pressure) is a hand-held gas pressure Handy. 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.
