Typical diagnostic uses:
Why a 3-Gas IR Analyzer for atmosphere diagnostics?
The PGA3000 Analyzer measures CO, CO
2
, and CH
4
. Carbon potential can be
calculated using furnace temperature and the relationship of these 3-gases.
Oxygen probe real-time measurement of the furnace atmosphere can be verified
by 3-Gas analysis.
In addition to being an excellent diagnostic device, the PGA3000 will provide the
necessary data to fine-tune your atmosphere control.

Endothermic Generator Diagnostics
♦ The effectiveness of the catalyst is measured by the CH
4
content. Less than
0.5% is an indication of properly functioning catalyst. Higher concentrations
indicate the necessity for either conditioning or replacement.
♦ Measuring the level of CO in the carrier gas allows correction of the % carbon
reading at the furnace.
Heat Treat Furnaces – Conventional Endo Gas
♦ Furnace atmosphere carbon potential (% C) can be verified with the
PGA3000.
♦ Measuring carbon monoxide (CO) and carbon dioxide (CO
2
) can show
possible problems (i.e. water leaks, air leaks, and radiant tube leaks).
♦ The PGA3000 measures the free methane (CH
4
) in the furnace atmosphere.
Heat Treat Furnaces – Nitrogen/Methanol Endo Gas
♦ The carbon monoxide (CO) level in the furnace atmosphere indicates the
effectiveness of the cracking of the methanol. Equilibrium of this reaction
CH
3
OH Æ CO + 2H
2
is temperature dependent.
Heat Treat – Oxygen Sensor Control
♦ Periodic verification of the performance of oxygen probes.
