CO Experts model 2004

Steve D._4

I've read enough to get motivated and buy a CO sensor.

Is the CO Experts model 2004 designed in 2004 or produced in 2004. I would hate to start off with a 2 year old sensor.

Steve,

they updated the design of the unit in 2004.

I called George Karr(the owner) and asked about the life of the co expert detectors and he assured me that the clock doesn’t start ticking on the sensor life until the unit is turned on. When I heard they were stopping the 2002 model (a much better unit) I bought a bunch of them. I still have about 3 cases left. I haven't had any problems with the older units at all and I feel much better about selling them to people with kids.

Can you enlighten me?

Since you seem to know the differences, can you tell us what changed in the design from the 2002 to the 2004 model?

As best as I can tell, the COExperts unit still alarms at much lower levels than UL 2034 calls for. But for some reason I believe that the 2002 alarmed with a tone at lower level than the present model?

Does the NSI3000 alarm at lower levels and if so, how much lower?

George changed the lower alarm level on the new models to 25ppm IIRC.

The 2002 models started warning at 10ppm.

Thanks Mark!

If I'm reading their online manual correctly, it's not possible to alarm the unit at lower levels. That's a pity and it would have been an inexpensive feature to implement. It's still a great detector though, and until NSI has enough contractors out there willing to carry the NSI product, I guess the COExperts unit is a workable alternative.

Jim Davis has stated earlier that they're getting more and more people certified, so the interest seems to be there... which bodes well for homeowner and contractor alike.

You're welcome!


I was told that George raised the alarm point due to complaints from airplane pilots. Apparently 15ppm is common in some planes.

It is still a better choice than anything that carries the UL seal.

Stay safe!

We sell to qualified contractors, not just certified ones. If the contractor doesn't carry a CO analyzer he is not qualified to respond to an alarm.
