CO2 monitoring - Hamilton Medical

The CAPNOSTAT-5 sensor provides technologically advanced measurements of end-tidal carbon dioxide (PetCO2) and respiratory rate, in addition to a clear, accurate capnogram at all respiratory rates of up to 150 breaths per minute. The mainstream sensor in combination with the Hamilton Medical flow sensor allows a volumetric capnography.

Carbon Dioxide CO2 Measurements | Vaisala

CO 2 is a colorless and odorless gas that is soluble in water. It is the bubbles in the fizzy drink, a greenhouse gas, a byproduct of burning reactions, and in the air we exhale. CO 2 is itself non-combustible and inert gas, which makes reliable measurement challenging. The most dependable method for CO 2 measurements is Vaisala CARBOCAP ® carbon dioxide sensor, an optical infrared ...

Atmospheric CO2 Data | Scripps CO2 Program

Measurements of atmospheric CO 2 concentration in our program began in 1957 at La Jolla, California and at the South Pole, and in 1958 at Mauna Loa Observatory. These measurements were gradually extended during the 1960's and 1970's to comprise sampling at an array of stations from the Arctic to Antarctica. The primary (in situ) record from ...
