maybe you checked with the home heating meter division of Kane, since I am strongly under the opinion that "KAL" is "Kane Automotive Labs" but I know of a few auto parts stores that carry a Kane tailpipe 1 gas sniffers...
and I have one, but I have had it for so many years that I would not expect the price (or current design) to be all that close to what I have.
If I was buying one today, in the USA, I might go to the northern tool web site; www dot northerntool dot com, and copy paste this to the last part of the URL ;
webapp/wcs/stores/servlet/product_6970_200318179_200318179

or search "exhaust gas analyzer" on their site.
