Question about the delay / response time for the CO-Experts Low Level Monitor


What is the speed of response of your CO monitor (ie: 90% of actual value within 10 seconds).  I ask this question because the UL standard on speed of response for  consumer CO monitors is terrible (ie: 70 ppm within 60 to 240 minutes).
What is the price of your monitor?

Thank you.


Thank You, for your Interest in my Low Level C O “Health” Monitor, …. and especially for your Question on “Detection / Reaction” timeframes.

My Monitor takes a “NEW READING”, every TEN SECONDS and features what I call IDR, [Instant Detection & Response].  There are NO “Time Delays”, or “Time Weighted Averaging” used.
In “Real Life Fact”, it does normally take 30 to 60 seconds to “Displace” the “Clean Air” from inside the Housing so the C O can actually get to the Sensor. The Sensor then updates the Digital Display Readings every TEN Seconds, as long as the C O is present above the Visual Display Level Requirement.

Please “Review” the New Model 2004 on my “New Products” section on my Website:

Pricing varies greatly, depending of the “Level” of Distribution involved.  Some have been sold for nearly $300.00. C  O – Experts has a “Suggested” Consumer price of $179.00.  [Not including Inspections, Installations, etc.]

Thanks for your reply.  I got an “education” on consumer CO alarms a few days ago.  We had a CO detector that went off and I immediately looked in the manual to first rule out a low battery warning.  The alarm was indicating the presense of CO so we called the fire dept.

They arrived with their CO meter and found no CO in the air around the furnace, HW heater, or coming out of any of the vents.

The firemen suggested I test our monitors by placing them around car exhaust.  So I did this and neither our AC or battery powered alarms responded after several minutes of exposure to the exhaust.  This made me suspicious about the alarms we had.  So, I went to the hardware store and bought a new alarm.  My wife began reading the back of the packaging for the new alarm.  She was surprised by the detection rates of the alarm.  The fire dept recommends leaving the premises if levels greater than 35 ppm are detected.  The CO detector takes 60 to 240 minutes to detect 70 ppm. Yikes!!!  What junk!!!  According to a collegue who used to work in the gas industry, CO poisoning is a cumulative thing.  In other words extended exposure to low levels is the same as a short exposure to high levels of CO.

So, I started looking into industrial grade detectors and found a variety of models.  I probably wouldn’t have taken my research this far if it
weren’t for the 2 month old baby we have in the house.  My wife and I haven’t decided exactly what we are going to do, but we are considering buying a “reliable” CO detector.

Please tell me a little more about your product.  Are you the developer?  Does it use forced air over the sensor?  How many units have you sold?
Are your customers mostly residential or commercial/industrial?  Who would we contact if we wanted to purchase your CO detector?

Has anyone independent of your organization done any product reviews on your detector?

Since we are skeptical of the reliability of CO detectors we would like assurance that our next CO detector is going to do the job it is placed in service to do – alert our family when the risk of CO poisoning first appears.

Thank you!!!

Would you please send me the telephone number of your Fire Department, and  if possible, the name of the “Person”, who told you to hold your C O Alarms behind your car exhaust.

This “Can Be” an EXTREMELY DANGEROUS thing to do.

Many C O Alarms are “Designed” to NOT ALARM until they have been exposed to 400 PPM, or more, for at least 12 1/2 to 15 MINUTES. [This is also covered on my Website.]

We are served by the Columbus Division of Fire.  The website containing a list of phone numbers is>.
I’m not sure who you should contact there regarding CO detectors.
