combustion analyzers

Ray_7

My company just purchased a Bacharach and the instructions state to not leave it in cold weather for a long period of time. It will damage the internal electrical components.

combustion analyzers

can combustion analyzers be kept in service vans overnight
durring below freezing temps.orr during the day for a few hours.i do commercial work,and if im not in a warm boiler room,im on a roof.the manual says not to be operated below 32,but states nothing on storage.i know the battery will die quickly,but is there any other problems with storing below 32.are any particular brands affected by cold storage.

any info would be appreciated

i bring my bacharach

in every evening, but leave it in the truck during the day.

It is not a good idea to keep an electronic

test equipment in extreme cold or hot environments. Many of the components are temperature sensitive when exposed for long periods of time. I have had digital meters freeze up on me when I was working for a long time on a roof with out using the meter. I learned to put it inside my coat to keep it warm. I actually had them not work at all or give erratic readings.

The reverse was someone left a combustion analyzer on top of the boiler and when we went to use it the readings were all over the place.

DO NOT


leave them in vehicles overnight in cold climates!

I sleep next to mine.

Just kidding, but we NEVER let that testing equipment sit in a truck overnight.

If you have to test in a cold environment, ok. the equipment can take that limited exposure. Leaving it in a cold van all night will greatly reduce the life of the equipment, not to mention your batteries. When the batteries get low, the equipment can do funny things.

Keep em warm, keep em safe.

Cold problems

One of the biggest problems for any combustion analyzer is moisture on the sensing cells. They just flat out don't like it. This problem is amplified greatly when using the analyzer outdoors, especially on condensing equipment with a high moisture content. If you have to use the meter under those circumstances make sure you give it a good long purge at the end of the test and do it in a room temp environment. This will greatly prolong the life of the cells.

The oxygen sensor is freeze sensitive and can get ruined if it gets cold enough. Learned this the hard way.

Not in the newer ones................

Just heard it from the Bacharach rep, Pete Cullens. THe newer units oxygen sensor is not cold temp sensitive. I can leave my unit in the truck overnite. They did have a problem a while ago and the older oxygen sensors are freeze sensitive.

I take mine in every night. As Steve said they are really sensitive to moisture. In fact I let mine run for about 5 minutes disconnected after every use just to let it dry out.

I'll speak from experience.

I have a Testo 300XL that I used to leave in the truck. One time I pulled it out of my cold truck and went to use it, and it just went crazy with readings, then stopped working all to gether. It also was wet everywhere with condensation. Once it warmed up and dried out (a day later) it started working ok, but shortly afterwords, I lost the O2 sensor, and the backlight on my display stopped working. Expensive lesson learned the hard way.

Left mine...

Was in Michagan this week, left my Fyrite Pro in the truck the past 3 nights, got down below 10 degrees every night.

Visited a customer this morning that burned 120 tons of sawdust a day for heat and to drive steam turbines for electricity (very impressive facility and a good bunch of folks!!)

The Pro worked fine although common sense tells me it's still a good idea to bring it in at night when it gets that cold and like Josh said, it's a good idea to post purge any combustion test instrument to remove moisture from the instrument (regardless of the temp).

Pretty impressive, they generate enough electricity for the plant (3,200 employees making furniture) and still produce twice the electricity they need for manufacturing, the rest is sold to the local electricy company.

The instructions may be old........

Most likely they haven't changed the instructions yet. Pete Cullens works directly for Bacharach and is our area rep. He said they fixed that problem with the O2 sensor and that it was ok to leave it in the truck. If you here it from a second source at Bacharach then it most likey is true. Call and ask tech support.

Inside-outside

I have carried combustion analyzers in my car for 25 years. My rule of thumb was bring it in below 10 degrees. Some analyzers will not operate if their internal temperature sensors are below 32 degrees. Batteries get very weak when they are cold. Moisture will freeze and plug the hose assembly and filters. Always disconnect probe assembly from analyzer during storage and open up water traps to let any residual moisture evaporate.
