Specification   :

Click to ViewNon-dispersive infrared gas analyzer with CO2 analyzer precision within 0.2 μmol mol-1 RMS at 1 Hz with 4 second averaging at 400 μmol mol-1 and H2O analyzer precision Within 0.01 mmol mol-1 RMS with 4- second averaging at 10 mmol mol-1 with operating temperature between 00 to 500C.

  Working Principles
Click to ViewIt is based on the properties of diatomic gas molecules, which have characteristic absorption spectrum in the infra-red region. Therefore, absorption of radiation by a specific hetero atomic molecule is directly proportional to its concentration in an air sample.The analyser is built on the principle of direct proportionality between IR absorbance and concentrations of the sample diatomic gas, in our case CO2 or H2O.

  User Instructions
Can be used for measurement of photosynthetic gas exchange and chlorophyll fluorescence measurements.As per Instructional manual and SOP
