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.
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.
