www.actoolsupply.com2. Long response times of NO 2, SO 2, H 2SCauses:Contaminated flue gas probe, probe tube, particle filter, gas cooler,... damp particle filter. Flow rate or pump capacity too low (NO 2issensitive to flow rate). Components for admitting test gas madefrom material that distorts the test gas due to absorption effects(e.g. silicone tubing with NO 2and SO 2). Hoses and test gas pipestoo long and internal diameter unnecessarily large in the admissionsystem.Remedy:Clean/dry the listed measuring system components or renew ifnecessary. To admit test gas use materials such as teflon andstainless steel (pressure reducer).Keep hose and pipe lengths and internal diameter to a minimum. Ingeneral, the smaller all the volumes in the system, the more precisethe gas calibration.3. Excessive deviation from additional analyserCauses:Different adjustment gases used in the Testo device and the otherunit.Different cross-sensitivities when mixed gases are used.Remedy:Use the same test gases (measuring ranges should be similar). Ifpossible, use test gases with only one component.www.actoolsupply.com29
