Instrument Solutions, a wholly own subsidiary of BSRIA, now supplies infra-red cameras for thermal imaging. The service is particularly useful for building inspectors as well as for heating engineers, builders and plumbers. Equipment such as the Flir B-series of compact hand-held imaging cameras can be used to detect energy loss and poor insulation, overheating electrics, moisture and air leakage in a building — as well as hot spots, non-functioning and leaking areas in central heating and underfloor heating systems.
