Key advantages of RTD INCOTEST
RTD INCOTEST provides a reliable solution for a variety of applications.
• RTDINCOTESTenablesthedetectionofCUI(CorrosionUnderInsulation)andFAC(FlowAccelerated
Corrosion).
• Riseraveragewallthicknesscanbegaugedwithoutremovingmarinegrowth,neopreneorMonel.
• Non-contact‘dry’wallthicknessmeasurementscanbecarriedoutevenwithdirty,coatedroughand/orhigh

• TherobustdesignofRTDINCOTESTiselectrically,althoughnotintrinsicallysafe.
• Operationispossibleacrossawiderangeofclimaticconditionswithconsistentlyhighlevelsofreproducibility.
• Measuringthroughanynon-conductiveornon-magneticmaterial,RTDINCOTESTdetectsandcalculates
