Attention:

LDM301 is equipped with two laser. The infrared laser for measurement operating at 905nm is a CLASS 1 Laser Product which is safe under reasonably foreseeable conditions of operation. The pilot laser is a CLASS 2 Laser Product operating in the visible red light at 635nm.

DO NOT LOOK INTO THE TRANSMITTER LENS!

DO NOT POINT THE TRANSMITTER LENS AT OTHER PEOPLES EYES!

DO NOT LOOK AT THE LASER BEAM USING OPTICAL INSTRUMENTS!

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.
