The OxyGuard Handy Polaris TGP is a hand-held meter that measures the atmospheric pressure, the total dissolved gas pressure, the oxygen partial pressure and the temperature.
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 are on the display, and menu functions, make the Handy Polaris TGP easy to use.
