The testo 805i infrared thermometer, in conjunction with a smartphone or tablet, functions as a compact IR thermometer for wall temperatures, as well as fuse and component temperatures in air conditioning systems. The measuring point is marked clearly with a laser circle made up of eight dots - so you always know precisely where to measure.

Documentation including images via App on a smartphone/tablet

With the testo Smart Probes App installed on a terminal device, users can view their readings conveniently. And that`s not all: the App can also be used to create and document images, including temperature values and laser marking. A separate measurement menu makes it easier to detect areas that are susceptible to mould. Particularly useful: a list containing the emission levels of certain materials is already stored in the App, so there`s no longer any need to waste your time looking these up in tables. All measurement data is displayed either as a chart or in table form. The measurement data log can then be emailed directly as a PDF or Excel file.
