    NOx and CO sensors

    Does anyone know of a nitrogen oxide and a CO sensor that gives a 0-10v or 4-20ma signal to a controller? I can't seem to find a decent one on any site.

    I've used MSA products. Nice but a bit pricey

    Intec Controls out of California. You can just get the sensors or can add an alarm panel with LCD, buzzers, etc. Their probably the best "Middle of the Road" gas sensor. Certainly there are cheaper ones out there and also more expensive ones.

    Honeywell Analytics are nice too.

    I just installed a number of ACI gas sensors for hydrogen, acetylene, ethylene, and oxygen. Had a few issues setting them up and they provided excellent support.

    Honeywell Analytics has the E3Point monitor. Has 4-20 ma output as well as can be a BacNet device. I have have put in 100s of them.

    As mentioned by others, the Honeywell Analytics E3Point and Intec Controls.

    I've put in bunches of both, some have been in for years. No complaints, work as advertised.

    I tend to favor Intec. They work well in my experience, pricing is a bit better. Good selection of devices and accessories. The E3Point stuff is good also, no complaints.

    Intec:

    A site where I stash some stuff that might be interesting to some folks.
