Emmissions Testing

09/18/2009 12:07 AM

Has anyone used, or is still using a Horiba MEXA-554J Series automotive emission analyser? I want to know where I can obtain the standard gas (HC, CO, CO2 and O2) cylinders to calibrate the instrument. From the illustrations in the instruction manual, the cylinders should be about the size of a standard size aerosol can (~250 mm L, ~80 mm Dia.) and they should have the standard gas concentrations marked on them.

And yes... I have tried Horiba (Singapore) - they've sent me size E gas cylinders with no fittings, regulators or adapters, etc.

Appreciate some advice/suggestions...

Cheers

Try this company, its where we get CEMS cal gases.

You'll probably need to have the gas standard number or the concentrations, something like 100PPM CO balance N2?
