Richeee Posted June 17 Report Share Posted June 17 My brother has emigtated to Cyprus. He was the previous custodian of the parts that is my 13/60 resto. Before he left he gave me his Gunsons Gas tester. Seen videos of it in operation. Seems a bit of a fiddle but with persistance results can be obtained. Trying to find approx figures for co2 for my 1500 spit on twin hs4's. The Haynes manual being quiet and the workshop manual stating 2.5 to 4.5. Any body had experience of these and what set theirs to.? Thanks Link to comment Share on other sites More sharing options...
Pete Lewis Posted June 17 Report Share Posted June 17 got one in the cupboard yes they take an age to heat up and can get stable results you need to keep the tubes clean. but its works i find my ears and nose work a lot quicker Pete Link to comment Share on other sites More sharing options...
Steve P Posted June 17 Report Share Posted June 17 But how do you convert a percentage into PPM that the Mot displays?. S Link to comment Share on other sites More sharing options...
JohnD Posted June 17 Report Share Posted June 17 PPM is Parts Per MIllion, per centage is parts per 100. 1,000,000/100 = 10,000 So divide the PPM by 10K. 5ppm = 0.0005% John Link to comment Share on other sites More sharing options...
