Found this in a pile of stuff I got at a Shop sale...

Anyone ever seen one or know what it does?

is that a break out box? i havnt seen a gm version of one, only chrysler, but i bet thats what it is, but its pretty old, 80's maybe. useful for diagnosis of electrical gremlins if it fits youre truck

agreed, looks like diagnostic equipment.
 
Ok, so at least someone know what it is!
Now, what year and models is it for?
I have searched the pat number and come up with nothing...
 
Awesome Nate!
I did search that pat number but came up with nothing...
The year makes sense, as I got something else at the same time from the same era...
This..

And 2 CO/NC Exhaust analyzers. This one and a smaller portable one..

They're cool shop talk items. If you have room to store them, put them in the corner. When you figure out how to use them. All your buddies and you will be drinking one night. Some one will say, "Lets see if we can get the Beckman to work."

The gas analysis system was composed of three extractive systems; a Total Hydrocarbon
Console, a Main Console, and a Background Hydrocarbon System.
Total hydrocarbons were measured using a Beckman Mode 402 heated analyzer equipped
with a Flame Ionization Detector (FID). Sampling was accomplished by probes in the
dilution tunnel. The sample was transferred via heated teflon sample lines to the total
hydrocarbon console. The main sample filters which protect the gas analyzers from
particulate matter were located in a heated compartment (190o C). A heated sample pump
extracted the sample from the dilution tunnel and delivered it to the hydrocarbon
analyzer.
The main console housed the Carbon Dioxide (CO2), Carbon Monoxide(CO) and heated
Oxides of Nitrogen (NO/NOx) analyzers. The sample was extracted from the dilution
tunnel, filtered in the total hydrocarbon console and transported to the main console
through heated teflon lines. The sample was then apportioned in the main console. Part of
the hot sample gas was analyzed by the NO/NOx analyzers; the balance was cooled and
dried by a condensation dryer. The cooled sample was then analyzed by the CO2 and CO
analyzers.
The following analyzers were used:
* NO/NOx Beckman Model 955 heated chemiluminescent analyzer.
* CO Beckman Model 867 non-dispersive infra-red.
* CO2 Beckman Model 864 non-dispersive infra-red.
* THC Ratfisch Model RS55, heated FID
All gas analyzers and related emissions equipment were calibrated using standard
procedures. This included instrument calibration prior to the start and frequently
throughout the testing day. Matheson Gas Products "Primary Standard" gases were used
for calibration (+/- 1% accuracy).
 
Yes, I also found a few references to the Co/No analyzer being used for high quality or reference tests and goverment/epa emissions work.
I also keep seeing remarks about calibration gasses...
