The 870-1 by Testo features an integrated fixed focus. All measurement objects from a distance of half a meter are presented in sharp focus. Manual focus of the infrared camera is no longer necessary. This allows you to concentrate fully on the measurement of the object. By pressing the trigger button once, the thermal image is saved.
