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 10ppm 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 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, 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 10ppm. Competitive analyzers typically take hours. ). As a result it is practical to accurately calibrate this analyzer on air and have it back on line within a very short time.

The AMI T-2 trace oxygen sensor is inherently faster than competitive sensors due to its metallic body and large active electrode area. It is also naturally resistive to hydrogen sulfide up to 10ppm H2S over its warrantied life, and may be used in samples containing high levels of CO2 with no ill effects.
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 (which significantly increases their come-down time. The 2001LC provides a standard set of features for trace oxygen analysis at an unprecedentedly low cost.
