With an NETD of < 50mK in the Testo 881and < 80mK in the Testo 875, the thermal imagers provide the highest thermal sensitivity and image quality in their price sector.
For tech geeks, they use a vanadium oxide digital microbolometer that has a NETD (noise-equivalent temperature difference) of less than 50 milli-Kelvin.
For at NETD were usually found those officers being returned to Canada for "Adjutant-General's disposal" and those Other Ranks being discharged as "unlikely to become efficient soldiers".
Benefiting from a research-grade thermal imaging camera with a large focal plane array detector that delivers low NETD and advanced design microscopic lenses, the stand delivers high spatial resolution, making microscopic thermal evaluation of electronic and photovoltaic components routine.
