1.0 Introduction
1.1 Overview
The Teledyne Analytical Instruments Model 7120 Analyzer, is versatile
microprocessor-based instrument.
The manual covers the Model 7120 Explosion Proof Bulk mounted
analyzer. Consisting of an Analysis section and Control Unit section. The
7120 Analyzer is for indoor or protected use in Explosion Proof environ-
ments only.
1.2 Typical Gas Applications
Typical applications of the Model 7120 are for ppm’s to % ranges:
• 95 to 100%CO2 purity for the Beverage Industry
Other gas purity applications are: 90 or 95-100% CO, 98-100%
C2H4 (ethylene), 90-100% CH4
(methane). Others possible, consult
factory.
• 500 to 2000ppm ranges of H2Ov in INERT GASES, CL2, COCL2, CO,
CO2, etc. % levels also possible.
• Chemical/Petrochemical: FCC gases, off gases, reforming/process gases:
CO, CH4, C2...C6, C2H4, etc.
• Ammonia Plants: Catalyst protection, process
control: CO, CO2, NH3
• Ethylene Plants C2H4 purity, CO, CO2, CH4
• H2, Syn/Natural Gas, Fuel cell plants 90 or 95%-100% CO purity, CO2,
CH4
• Iron plants or Metal Processing Coke, Blast, Electric furnaces:
CO, CO2, CH4
• All Industries Drying ovens, moisture control
