Oxyguard DO meter

[Gerryd]

Hi Tom,

Any thoughts on this model? Or do you have another recommendation?

Model 840

BTW, I am going for the stationary c02 meter.......would like to kill two birds with one ordering stone, so to speak.

Many thanks in advance.

You realize that is a O2 meter, not a O2 meter correct?

Tom,

??????

The DO meter is for 02 oxygen correct? I thought this would read oxygen levels in the water.....

I am ALSO getting the C02 (carbon dioxide) meter.

You use 02 BOTH times in your reply?
