THERMOPOINT is a unique analyser that can be used with any thermal camera. The ambition is that it will become a must-have measurement tool for energy auditors. Recent modern buildings have envelopes made of glossy panels. THERMOPOINT allows contactless evaluation of real surface temperature emissivity, which is needed to compute a building’s energy loss. The product consists of an infrared radiation source freely positioned in a space and a detached computing unit (smartphone or tablet). The IR source is controlled from the computing unit via Bluetooth. The computing unit allows temperatures read from the screen of a thermal camera to be entered, and calculates and visualises real temperatures and the emissivity.
