AMI - Model 2001RS/RSP -Advanced Trace Oxygen Analyzer
The MODEL 2001RS and 2001RSP are advanced Trace Oxygen Analyzers loaded with a full suite of standard features. The Analyzers’ compact design includes AMI’s patented ELIMINATOR CELL BLOCK technology, incorporating a complete sample system, and combines it with our industry-leading trace O2 sensors. This combination delivers accurate, reliable and extremely fast response times in a panel mounted, virtually maintenance-free package.
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. The patented design 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. For simple certified gas calibrations, we have provided a surface mounted 3-way gas solenoid valve – activated from the front panel interface.
The MODEL 2001RS and 2001RSP are loaded with a full suite of advanced features without the typical ‘up charges’. The standard features include: 10-user selectable analog output ranges, dual independent alarm relay contacts, comprehensive alarm logic, alarm bypass, and 3 levels of security settings. The data logging feature provides detailed time-stamped records for O2 measurement, temperature, supply voltage and power brown-out history. Additionally, the 2001RS/RSP analyzers have integral solenoid valves for O2 sensor protection during unexpected power loss.
AMI’s patented oxygen sensors deliver unmatched performance for ultra-fast response times, accuracy, and reliability. Every sensor undergoes an intense battery of testing to ensure they meet our strict quality control standards. Our trace and percent oxygen sensors operate safely, accurately, and reliably in inert or flammable gas streams. For particularly difficult applications, our sensors can tolerate high levels of H2S, up to 500 ppm H2S, for their entire warranted life. This eliminates installing a maintenance intensive H2S scrubber that competitive oxygen analyzers require!
The MODEL 2001RS is designed for trace oxygen measurements in positive pressure applications, while the MODEL 2001RSP includes a sample pump making it the perfect choice for measuring trace O2 measurements in atmospheric or vacuum conditions.
