Technical highlights of the testo 865 thermal imager

The testo 865 thermal imager stands out thanks to its easy operation and has the following impressive technical features:
 
  • Very good image quality due to high resolution: 19,200 temperature measuring points ensure precise thermography. Infrared resolution of 160 x 120 pixels – via integrated SuperResolution Technology 320 x 240 pixels
  • Visualize temperature differences from 0.12°C
  • Critical temperature conditions are directly displayed via automatic hot-cold spot recognition
  • The IFOV warner means the distance from the measurement object / measurement spot size is determined and the measurement spot is shown on the thermal image – you therefore avoid measurement errors because the camera shows you exactly what you can measure
  • Pro software for image evaluation on the PC
  • You can choose to save thermal images as JPEGs

Odkrivanje konstrukcijskih pomanjkljivosti in zagotovitev kakovosti gradnje (posebej: neprepustnost zraka na oknih in vratih)

Analiza s pomočjo Testo termovizijske naprave je hitra in učinkovita metoda odkrivanja morebitnih strukturnih poškodb. Naprej, Testo termovizijske naprave so popolne za ponujanje dokazov o kakovosti in pravilni izvedbi gradbenih ukrepov. Vse toplotne izgube, vlaga in prepustnost zraka v stavbi so razvidni na toplotni sliki. Testo termovizijska naprava omogoča odkrivanje nepravilne toplotne izolacije in poškodb konstrukcije - vse to pa z uporabo brezkontaktne metode! Funkcija testo ScaleAssist, ki avtomatsko zagotavlja optimalno nastavitev merilne lestvice toplotne slike, pomeni, da ste dobili objektivno primerljive toplotne slike stavb. Funkcija dodatno olajšuje oceno strukturnih poškodb in toplotnih mostov. Preverjanje neprepustnosti zraka na oknih in vratih je ena izmed tipičnih uporab termovizijske naprave.

Enostavno preverjanje ogrevalnega sistema in instalacije

Testo termovizijske naprave so enostavne in intuitivne za upravljanje, zato so popolne za hitro in zanesljivo preverjanje ogrevalnega sistema, ventilacije in klime. Zadostuje hitra uporaba termovizijske naprave, da odkrijete nepravilnosti v razporeditvi temperature. Tako se termografija lahko uporablja za enostavno lociranje zamašenih radiatorjev in uhajanj. Tipične uporabe termovizijske naprave:
 
     Preverjanje usedline v radiatorju
    Odkrivanje uhajanja
    Merjenje temperature pretoka in vračanja
    Določanje poteka zank ogrevanja v sistemu talnega ogrevanja
 

 

Na sledi razpokane cevi

Če obstaja sum razpokane cevi, edina preostala rešitev je odpreti cela področja stene ali tal. Termovizijska naprava vam omogoča, da zmanjšate škodo in zmanjšate stroške, ker natančno locirate uhajanja v talnem gretju ter drugih nedostopnih cevovodih. Na ta način se izognete nepotrebnem odpiranju sten in tal ter znatno zmanjšate stroške popravila.
