CO / VOC / Methane detectors? not alarms but actual measuring instruments

I have an air things air quality monitor. It is showing peaks of CO2 and VOC's at various times. We just replaced our furnace and hot water tank. The old ones were atmospheric vented, now each have their own air supply from outside. We also have a couple sealed gas fireplaces. In the graphs Nov 4 was the replacement date but you can see the numbers are improving but still not great. I want to more carefully check the new and old equipment for leaks of exhaust and methane as I can't explain the peaks and valleys especially well. Can anyone recommend inexpensive & relatively reliable gear for this task? There are cheap solutions on Aliexpress for $40 to $80 and more. There are single function devices available at princess for $100-$150. and probably better gear for a lot more from specialist sources... I don't want an alarm. I'd like some sort of "sniffer" that I can check equipment, furniture, rugs, etc.

CO2 is carbon dioxide, CO is carbon monoxide. methane, as far as I know is not in the exhaust from appliances or vehicles burning gas etc.
VOC, voalatle organic compounds should not be coming from the furnace or hot water tank. Generally from new carpet, paint, possibly some types of glue. Maybe paint on furnace??
What is the gray/light blue on the graphs?
I have no experience/knowledge with equipment that can measure VOC.
The equipment we used measured CO, Ocy, flammable gas levels, and I believe hydrogen sulphide levels, in one unit. No idea what they are worth now, then I think about $ 1500.00 each. Some others that were available, $400.00 —$800.00+/-, generally didn’t have replaceable sensors.
We also used a flammable gas detector that could pin point a gas leak from joints etc., it would also pickup rubbing alcohol etc. as that gave off flammable vapers.
 
Apparently incomplete combustion
can have VOCs and methane in it.

The grey blue is the peaks whereas the line is an average.
 
The inspector came yesterday to inspect the new garage furnace and it passed although he said it needs a sticker derating the furnace due to Calgary’s elevation and said it’s probably drops to 55,000 from the advertised 60,000 BTU.
