Model 201LC

Low Cost Percent Solution For General Purpose Environment

The MODEL 201LC is a compact, cost-effective solution for measuring percent oxygen without sacrificing accuracy or reliability. The 201LC is designed for general purpose, panel-mounted applications and is outfitted with a complete sample system using AMI’s patented ELIMINATOR CELL BLOCK™ and ultra-fast oxygen sensor technologies. Key features include simple front panel sensor access, compact size, 4-user selectable analog output ranges, 2-independent fully adjustable oxygen concentration alarms, and an isolated 4-20ma output, and the unit is virtually maintenance-free.

ELIMINATOR CELL BLOCK™ For A Leak-Free Design

The patented ELIMINATOR CELL BLOCK™ provides a unique, compact sample system approach and a flow-efficient sensor pocket machined into a solid metallic block. Precision cross-drilled intersecting gas passages eliminate the need for long lengths of tubing and leak-prone compression fittings. Additionally, we have engineered the metering valve and flow meter to be an integral part of the ELIMINATOR CELL BLOCK. It also provides the user with direct front panel access for installing and replacing sensors, and the ability to air calibrate the Analyzer, all without the need for disassembly or tools.

Proprietary Sensor Technology

The 201LC combined with AMI’s patented oxygen sensors deliver unmatched performance for ultra-fast response times, accuracy, and reliability. Every sensor undergoes an intense battery of tests to ensure they meet our strict quality control standards. Our trace and percent oxygen sensors operate safely, accurately, and reliably in virtually all gas streams.
