TGA200 Trace Gas Analyzer Overview
The TGA200 Trace Gas Analyzer measures trace gas concentration in an air
sample using tunable diode laser absorption spectroscopy (TDLAS). This
technique provides high sensitivity, speed, and selectivity. The TGA200 is a
rugged, portable instrument designed for use in the field. It can measure one of
a large number of gases by choosing appropriate lasers and detectors.
