DESCRIPTION
The Nova 600 Series Portable Single-gas Ambient Air analyzers are convenient and accurate portable
instruments for monitoring toxic gas in ambient air samples. A built-in pump draws in the sample gas where it
is analyzed by the sensor. The detector output is then amplified and displayed on an easy-to-read digital
meter.
A choice of gases is available including H2S, SO2, Cl2, HCL, or NH3. An O2 sensor may be added to the single
gas versions to produce a toxic gas plus oxygen deficiency monitor. The electrochemical sensors utilized in
the 600 Series have a long service life of several years.
