ReportApp reads combustion measurements from Bacharach's Insight Plus and InTech combustion analyzers via QR code. Measurements can be viewed, saved, and emailed in pdf and csv file formats. A pdf report may contain a single combustion record, or it may contain two records in an "As Found/ As Left" report, showing the state of a combustion appliance before and after a service call.QR Code is registered trademark of DENSO WAVE INCORPORATED.
