The new EURO III/IV and ULEV/S-ULEV exhaust gas regulations also affect the concept of operating and calibration gas supply systems to a great extent.
In order to transfer low calibration or span gas concentrations in the lower ppm level from the gas cylinder to the analyser without changes in concentration, the gas supply system must fulfil certain minimum requirements. JAG has reacted to the future demands on exhaust measuring techniques by developing a new span gas supply concept for exhaust measurement as a turnkey solution.
