Any person have experience with some old style gas analyzers for car exhaust? Now we have 5 gas analysers for CO, CH, O2, CO2, NOx. OTC makes MicroGas for $7000. Snap-on Tools also has one for $7000, Autologic $3000 They are just good for auto mechanic shop and smog shops. Before there were 4 gas analysers only : CO, CH, O2, CO2 and no NOx. But before that, in 1970-1980-1990 there were some "one gas analyzer" , just CO. namely Heathkit, Sears, Inficon, even now still has Gastester, Gunson cost about $100, Kane-May, Halibar, RKI, Motortest, Peerless, AirFuelMixture What are they good for? I suppose that they do not really work, and now they just drop out of the market?
