Attention:

LD90 is a CLASS 1 Laser Product which is safe under reasonably foreseeable conditions of operation.

DO NOT UNNECESSARILY LOOK INTO THE TRANSMITTER LENS!

DO NOT UNNECESSARILY POINT THE TRANSMITTER LENS AT PEOPLES EYES!

The invisible laser radiation INSIDE the instrument may exceed the accessible emission limits of laser class 1, thus never open the instrument's housing  and never operate damaged instruments.

Aligning the infrared laser instrument LD90 with the lenses of CCD-cameras or infrared night vision devices can result in damage to them.

Summary

The Greenhouse Gas Analyzer (model GGA-24EP) is an advanced instrument for simultaneous measurements of methane (CH4), carbon dioxide (CO2) and water vapor (H2O) using cavity enhanced laser absorption technique.
