Measure principle
The
principle of operation of the toxic gas sensor is based on electrochemical
cells which are micro fuel cells designed to be maintenance-free and
stable for long periods. They have a direct response to volume
concentration of gas. Gas diffusing into the sensor is either oxidized or
reduced at the sensing electrode and, coupled with a corresponding (but
converse) counter reaction at the other electrode, a current is generated
through the external circuit. A capillary diffusion barrier controls the
rate of gas which enters into the sensor, therefore the current generated
is proportional to the concentration of gas present outside and gives a
direct measure of its concentration.
Analyzer's functions
The
analyzer, powered with rechargeable (3 weeks continuous measuring time )
batteries, measures the gas concentration and the value is:
Data-logger
Connecting
your PC to the PORTOX via the serial included cable, you can download the previously
registered data, view real time data measured, and setup the data saving
(second or minutes frequency and start up time).
Using
the dedicated software, included, data should be analyzed both in chart or
graphical view.
With
simple proper tubing is also possible to measure the chosen gas in the human
breath. More than other is the measuring of the carbon dioxide in smokers
breath. Knowing how much Co remain in the smokers blood, as
Carbon-oxide-Hemoglobin, should be one of the most important matter
in stop smoking.
The
analyzer is also provided with a recharger to be powered with 230 Vac.
