OP-2 - Open path CO2 analyzer. This is an enhanced version of the Dr. Steve Roberts design. The OP-2 is a folded path, open to the air, Infrared gas analyzer for measuring instantaneous CO2 and H2O concentration changes in the atmosphere.

OPEC - Open Path Eddy Covariance System This is an integrated system that uses the OP-2, a Windmaster sonic anemometer, and EDDYSOFT software developed at the Max Planck institute.

Lambda T - CO2 Monitor - Controller for green houses, laboratories, growth cabinets and any application where elevated levels of the gas are required. The Lambda T is a high accuracy CO2 monitor employing a novel twin wavelength, non-dispersive, infra-red, optical technique. This highly stable analysis allows the Lambda T to be used for unattended long-term measurement and control of carbon dioxide.

PGA - Portable Gas Analyzer The PGA is a simple reliable absolute analyzer for a variety of geoscience applications. Designed for field use, this product can be ordered for single or dual gas measurement.
The PGA can be fitted with an Infrared Gas Analyzer to measure one of the following gases: Carbon dioxide, carbon monoxide, sulfur dioxide, sulfur hexafluoride, nitric oxide, nitrous oxide, ammonia, methane, ethane, propane, butane, pentane, hexane, heptane, freon, hydrogen and hydrogen or sulphide The PGA can also be fitted with a paramagnetic analyzer cell for oxygen and dual gas analysis.
