AMI - Model 201LC -Percent Oxygen Analyzer
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.
Exceptional Value
The MODEL 201LC is the perfect low-cost solution for percent O2 measurements requiring a complete sample system and limited key features. It offers the same reliability, accuracy and repeatability of other AMI analyzer while including multiple output ranges, dual independent alarms, and intuitive controls. This virtually maintenance-free oxygen analyzer is a very cost-effective option for general purpose applications.

AMI’s patented cell block allows the analyzer to be built with almost no possibility of internal leaking, with minimal volume and with front-panel sensor access. All sample handling components – the flow meter and needle valve – are integrated into a solid metal block. Connections between them are drilled passages. The result is a highly reliable sample system with all necessary components provided. As a result it is practical to accurately calibrate this analyzer on air. Different sensors are available for gases containing CO2 or H2S.
The sensor is immediately accessible on the front panel of the analyzer, and can be replaced in seconds. It is not necessary to expose the sensor to air unshorted while installing it as is the case with most analyzers. The 201LC provides a standard set of features for percent oxygen analysis at an unprecedentedly low cost.
