First, the phenolphthalein indicator was added to the sample, but no colour change could be observed. Second, the green-methyl red indicator was added to the brine sample and titrated with H2SO4 acid (cartridge 1.6 N) until the green turned to a light pink end point. The number of ...
A short cut review was carried out to establish whether colourimetric carbon dioxide detectors are as reliable as capnometry at verifying tracheal placement of endotracheal tubes after emergency intubation. A total of 69 papers were found using the reported search, of which four presented the best...

This sensor has a traffic light feature to let you know when a certain threshold of CO2 levels, or any other value, has been reached. The threshold value is configurable, and you can choose the colour of the light, the frequency, and the light intensity. ERS CO2 relies on industry-...

extremely effective and suppresses the fire by oxygen depletion, thus creating a surrounding atmosphere where combustion processes cannot be sustained. Physically the CO2 is an electrically non conductive, odourless and colourless gas. It is heavier than air and does not leave residuals upon discharge...
