CompuFlow® 8650 CO2 Meter
Analyze the conditions of your indoor environment: carbon dioxide levels, temperature, humidity, wet bulb, and dew point temperatures. An optional RTD temperature probe gives the user the flexibility to take actual wet bulb readings or a second ambient temperature.

The 8650 stores data and can show the average readings in addition to minimum and maximum values. It has a datalogging feature to take measurements over an extended time period-a very useful option in understanding occupant trends. The optional 8522 MicroPrinter can be used with this meter to record readings; all readings can also be downloaded to a computer.
