Product FAQs

How often do I need to send my analyzer in for repair?
UEi recommends annual calibration for flue gas analyzers.
How do I use this analyzer?
UEi includes typical test locations and target values as a general guide, but recommends consulting with equipment manufacturers for exact guidelines. We also have available a demonstration DVD that shows the Eagle/EagleX series in use on a variety of equipment. Some of the tests from this video are posted on You Tube.
How long do the sensors last?
This varies by model. Our newer models use IR based sensors with an expected life of 10 years or more. The CO sensors in these newer units have an expected 5 year life. Our traditional electrochemical sensor based analyzers have a one-year warranty on the sensors, with an expected life span of two years.
How do I send the analyzer in for repair?
UEi uses UPS, but accepts shipments from US Mail, Fed Ex, UPS and others. Please contact UEi to receive a return tracking number or complete the online request from our web site. We will provide instructions and an estimated cost based on the information you provide.
Can I store my combustion analyzer in my service vehicle?
UEi recommends storing in a moderate temperature between 32~100F. If the temperature is expected to drop significantly below freezing or excessivly high it is recommended that the unit be brought inside.
How often do I need to change the particle filter?
Particle filters need to be changed based on use and the type of fuel. Natural gas burns very clean and will not block the filter fast, while heavy oil and solid fuels will require more frequent changes. Most of our filters will plug from the inside core out, and must be inspected to determine if they need changing. If the inner surface is black from soot it needs to be changed.
Why is my analyzer not showing a value for CO2 (or O2 on EOS based analyzers)?
Check the water trap drain plug to veify it is place. Also test the pump flow by briefly blocking the tip of the flue probe or blocking the inlet on the water trap. When blocked you should be able to hear the pump speed change and feel suction from the pump.
How do I test the temperature function on my analyzer?
If you have a second thermometer and water you can compare readings. Connect only the thermocouple connection from the probe, and submerse the tip of your probe in the water. Submerge the second thermometer and then compare readings between that thermometer and the gas analyzer. If the readings are off by 4 degrees or more please return to UEi for calibration. Small variances in flue temperature readings will have very little impact to calculated values of efficiency.
How can I test to determine if my CO sensor is responding?
Note - Do not test with automotive tailpipe exhaust. To perform a quick check of the CO use a paper or wood match or small piece of paper. Light the match or paper then extiguish it. Allow the analyzer to draw the smoke into the probe or bottom of the water trap. This should give you a reading of 50~100 ppm if you are able to draw in sufficient smoke. It should then return to zero within 3~5 minutes.
What are symptoms that my CO sensor is not functioning correct?
If the meter does not indicate any CO in the flue, or the readings are unstable. Do not test in auto or vehicle tailpipes.
The connection between the probe and water trap on my analyzer is broken. What is the part number?
The connector is part number is SM11103.
Why won't my analyzer turn off?
UEi analyzers will not power down unless CO is less than 20 ppm, and O2 is above 18% to protect the sensors. Contiue to purge the instrument in fresh air until readings return to near normal zero state (0 ppm for CO, 20.9 for O2). If you have a failed sensor it may prevent the analyzer from shutting down. Please contact UEi to arrange for service.
What is the upper limit for CO on my analyzer?
These models have an upper limit of 2000 ppm. It is not recommended to exceed this level, or operate at an extended time at this level. If the measured values are increasing quickly toward this limit, remove the probe from the flue and make appropriate repairs to the system before testing again. CO levels above 1000 ppm typically indicate that something is out of adjustment.
How do I know if my O2 sensor has failed?
The O2 sensor is set to 20.9 during start-up. An expired sensor will possibly show all dashes "- - - -" instead of 20.9. Other indications are that the value will initially be 20.9, but then increase to a higer value such as 25%. Rapid changes of large amounts are also an indication such as dropping from 20.9 to 15%.
