The PG-250 and PG-235 are portable, self-contained gas
analysis systems that simultaneously measure multiple components.
Measured Components:
PG-250 NOX, SO2, CO, CO2, O2
PG-235 NOX, CO, O2
Unlike other portable gas analyzers that rely on electro-chemical sensors, the PG-250 and
PG-235 utilize the same measurement techniques as a permanently installed CEM system.
These include chemiluminescence (CLD) for NOX,
non-dispersive infrared (NDIR) for CO, CO2 and
SO2.
More importantly, the PG-250 meets or exceeds the regulatory requirements of federal and
local environmental agencies.
These instruments weigh in at 37 pounds, and have overall dimensions of approximately
10" x 10" x 20". Their size makes them ideal for stack testing, and the
performance characteristics justify their use as a back-up CEM system.
