Hello,

Do I understand you are looking for a handheld, portable meter that will measure 100% concentrations of CO2? That's a pretty incredible atmosphere - way, way toxic. Try Mine Safety Apparatus (MSA) or Bacharach Instruments. They should have something in the lower levels and might have a high level one or be able to tell you where to look.

Google Drager, they make a range of monitors.

Try Crowcon Detection Instruments at www.crowcon.com.

They have IR Detectors that may do this measurement.

This may work for you. It is designed to test food packages where the product is flooded with CO2 to extend shelf life. They say they make these with a 100% CO2 range.
