===================== This 'Gunson' tester can be found in many shops :
Unfortunately it is only accurate to +/- 0.50% CO and so is only of use to older carburreted cars, pre '93 emissions standards. With fuel injected engines >0.30% is a fail :(
If anyone knows of a more accurate CO tester, say +/- 0.10% CO, that doesn't cost the earth I would be interested.
I wonder what the performance of a common or garden canary is.
Or a heating engineers one
Not so. The factory spec on my SD1 EFI is 1.5% CO. The difference is the date. After '93 cats became the only way to meet the regs.
From TFA:
"Measurement range 0 to 1000ppm"
So that's a measurement range of only 0-0.1% (1000 parts per million)
I guess if it's under that you'll definitely pass, but it's not much use for testing cars :-(
I suppose, if it will take a small volume of gas, that you could dilute it. Take a 10ml syringe, a 100ml bottle, fill the 10ml syringe with exhaust gasses, suck into the bottle, shake well, and squirt into the sensor.
