Industrial Analyzers

What is the upper limit for CO on my analyzer?
When using the standard configuration on these models, the upper limit is 10,000 ppm. Options are available to use on internal compustion where the CO level is measured in percentage and can read to 4% or higher. Please contact UEi for details.
How do I know when my analyzer needs its next calibration?
If the analyzer has been in for service to UEi there will be a calibration label with the next calibration due date.
