Hand Held O2 Meter

Handy Polaris TGP

The Handy Polaris 2 TGP is a hand held gas pressure meter.

The user can choose which value is shown in large figures in the display. This can, for example, be the % saturation value for gases other that oxygen.

 

The Handy Polaris TGP is a hand held gas pressure meter. It can operate in three modes, one where it acts as a standard Polaris dissolved oxygen meter, one where it is a Total Gas Pressure meter that shows pressures as “per cent 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 % saturation value for gases other that oxygen.

 

The instrument incorporates a data logger. Messages on the display and menu functions make the Handy TGP easy to use.

 

Advantages

The Polaris 2 TGP is designed for easy use and to give accurate here and now measurements of the Total dissolved Gas Pressure. The instrument also has a dissolved oxygen and temperature sensor and can display values of Total Gas, Dissolved Oxygen and Residual Gas, i.i. gas other than oxygen. These can be shown as % saturation values or as volume % values.

The Handy TGP can also be used as a standard Polaris 2 DO meter.

Maintenance is easy. The DO measurement is made using the well-known Handy Probe, and the TGP measurement tube sensor element can easily be exchanged if necessary.
