Explorer is a portable, automatic gas analyzer for identifying airborne chemicals
and measuring their concentrations.
Explorer uses a gas chromatograph (GC) to analyze air samples, but you do not
need to understand the principles of chromatography to operate Explorer. Explorer
collects a sample of air and automatically introduces the sample into the GC.
Explorer manages the gas flows and timing during the analysis, and compares the
outcome of the analysis against the outcome of a previous analysis of a calibration
standard of known composition.
Explorer then reports the analysis results on its
display, by compound name and concentration. Explorer alerts you with audible and
visual alarms if any of the detected chemical compounds have exceeded your alarm
concentration set points.
Explorer stores the analysis results in its internal
datalogger.
