efficiency test

jaybee

after doing a efficientcy test and get my readings how do i know if i have safe levels of carbon monoxide if im testing for draft,CO2,smoke,and stack temp?Is there a relationship between co2 and carbon monoxide,how does this concept work?

jaybee.....

...most combustion analyzers will also measure CO. The Bacharach Fyrite Pro 125 is the model we use, and it has an optional printer that can provide you with instant documentation of your readings.

Glad to see you asking so many questions, my friend. You obviously are trying to learn, and this is a great place to get an education. You might want to browse over to Bacharach's training web site. It contains several excellent articles on combustion testing, CO, and equipment.

Starch said it


You need a digital analyzer to test for CO. The CO2 numbers you are getting with the shaker bottle will not be an indicator of CO levels.

A Bacharach fyrite pro 120 will let you test combustion and give readings for 02, CO2, CO. The 125 gives you draft, but I prefer the Dwyer draft gauge.

Take a look at Bacharachs website, and I would recommend that you look into taking one of Jim Davis's classes on Combustion and CO.

Mark,

Why do you prefer the Dwyer guage over the Pro125?

Just Curious

I don't have a good reason


Starch. Just habit I guess?

I have also used digital manometers, but the whole "pascals to inches of H2O" is a pain.

Nothing wrong with the 125 draft though.

Don't tell anybody!!

But when I have the opportunity to run a service call, I still use the 460 air meter. Not sure exactly how 'accurate' it is - just a little plastic ball in the tube...

But I still like to let it hang in the stack while I'm recording the analyzer's CO reading on light off to see how quickly draft is established.

Then I'll use the electronic to double check the overfire draft and set up the baro.

For $30, it's a nice little gauge to have handy.

Does it

fit in the Fyrite Pro 125 case?

I've had my Fyrite Pro for a year and a half now and i must say its the most powerful tool I own.

I totally agree on the Dwyer

gauges as the best in-the field, love my Magnehelics.

Before you buy check everything out, Testo oxygen sensors can be changed in the field and do not require a factory down-time, FACT!

Go here:

Buy what you think is best, but test, test, test!

Rudy

Absolutely

It's really small, about 1" wide X 1/2" thick X 6" tall.

NCI sells them, there's a picture and info at:

Test is right George!


Testo makes good equipment as well. I just cut my teeth on Bacharach.

BTW, I changed the O2 sensor in my Bacharach while sitting in Jim Davis's class. No need to send them to the factory, they are also field replacable.

I'm glad to hear that,

I've recently had several people in seminars tell me that they could not! They were told to return them to the factory for replacement and 'calibration' and that they could not purchase sensors.

I know what you mean about Bacharach, I still use the wet-kit I bought in 1967 to teach with. In my position I show and teach them all, kinda have to!

I still have a Dwyer wet-kit just in case, but don't end up needing it on the East Coast. Did a group in Idaho 3 years ago, that's what they all had, amazing.

The oil industry has been very slow to admit to the very presence of CO. I first brought it up in 1978 at a NAOHSM panel, they wanted to kill me, how things change. Sometimes I feel like I'm talking to a group of pharaohs, they is all in DENile.

Robert O'Connor_6

Thanks for the

info Rudy!

Best Regards,
Robert

I think

the advantage of sending it to Bacharach may be that they certify that it is calibrated. I hope I never need that paper but it's good to have!!

Calibration


You do not need to calibrate the O2 sensors.

The only calibration is done to the CO sensor.

Hope this helps!

Testo has

A CO calibration kit you can use in the field after you change the sensor and I think Bach, does also.

Mark Hunt

Yep


You are correct sir!
