Since 2004 the Model 2010BR has been the unquestioned market leader, the industry-standard hazardous area trace oxygen analyzer. Over the years it has been continuously refined to the point that it now provides every feature you can possibly need – and many that you may not have thought of - in a compact, easily installed low-cost package. Many thousands of these analyzers are operating to specification in the harshest environments all over the country.
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 a four-way sample/span/off selection 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.
The AMI oxygen sensor is inherently faster than competitive sensors due to its metallic body and large active electrode area. The standard T2 sensor is also naturally resistive to hydrogen sulfide up to 10ppm H2S over its warrantied life, while the T4 is capable of resisting up to 500ppm H2S, with no scrubber material required, and hence no maintenance or leakage issues.
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). As a result, although a span gas port is provided, it is practical to accurately calibrate this analyzer on air in less than a minute.
For low temperature operation an integral (approved) explosion-proof heater can be supplied. This unit directly heats the cell block and thus is extremely efficient, allowing operation off a solar panel system down to -20F. It does not require additional enclosures or wiring. For extreme environments down to -40F, an outer insulated enclosure can be supplied, but no additional power is required.
The analyzer is approved by CSA for operation in a Class 1 Division 1 Group BCD hazardous area with a flammable gas as the sample. No additional safety barriers are needed. The analyzer can be calibrated and sensor replaced without declassifying the area because the analytical electronics are intrinsically safe, protected by internal safety barriers.
The electronic and software package is exceptionally complete, and all features are provided as standard with no additional cost (except for the heater). Even with the heater it is capable of operating off a battery and solar panel, and it logs power brown outs and failures should they occur. It also logs the ambient and the sensor temperatures so can be used to alarm on the failure of a catalytic heater if one is used in a remote location. It tracks the life of the sensor, indicates the remaining life, logs the calibration history and logs the oxygen readings over its operational (output) range, and also tracks excursions of up to ten times that range.
The analyzer can be wall-mounted with 4 externally accessible screws, or bolted to a 2” pipe using standard U bolts.
