Model 2001RS Oxygen Analyzer

The AMI model 2001RS is the ideal solution for measuring trace oxygen in a wide range of applications in a general-purpose environment. 

In a compact size, and at low cost, it provides a comprehensive electronic package and sample system using AMI’s patented cell block technology. 

In addition the 2001RS uses internal surface mount solenoid valves for sample/span gas selection and to seal off the sensor in the event of loss of power. 

Unlike competitive analyzers, AMI sensor replacement requires minimal downtime due to the front panel sensor access and the patented AMI cell block. 

Typical time from a one minute air exposure to 10 ppm is under 15 minutes. 

Trace oxygen analyzers are essentially leak detectors. 

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, needle valve and the surface mount span/sample selection and seal-off solenoid valves – are integrated into two solid metal blocks. 

The result is a highly reliable sample system with all necessary components provided, and a very fast “come-down” time. 

When a sensor is replaced, or calibrated on air with a 1 minute exposure (at 70° F), it takes about 15 minutes for it to come down to below 10 ppm. 

Competitive analyzers typically take hours. As a result, although a span gas port is provided, it is practical to accurately calibrate this analyzer on air and have it back on line within a very short time.
