Product Description

We developed the testo 871 thermal imager together with our experienced professionals to enable you to work quickly and easily with professional thermal imaging technology. You can generate error-free and objectively comparable infrared images using its handy functions. The IFOV warner, testo ɛ-Assist and testo ScaleAssist mean you can avoid measurement errors and not only effortlessly achieve optimum setting of emissivity (ɛ) and reflected temperature (RTC) for building thermography, but also of colour scale.
 

The testo 871 thermal imager– smart and networked

The testo 871 thermal imager communicates wirelessly via WLAN with your mobile terminal devices. The testo Thermography App for iOS and Android offers you the possibility of writing and sending reports on site, as well as saving them online, and of using your smartphone or tablet as a second display or for remote control.

The testo 871 delivers even more informative thermal images in combination with the compatible 770-3 clamp meter and the testo 605i thermohygrometer. Both are available separately – simply order them straight away along with your testo 871. The measurement results of both measuring instruments can easily be transmitted via Bluetooth. The additional output, current and voltage values of the testo 770-3 clamp meter enable better interpretation of measured temperatures. Measure the air temperature and humidity with the testo 605i and easily detect locations at risk of developing mould using the special humidity palette in the thermal imager via the traffic light principle.
 

Areas of application of the testo 871 thermal imager

Detect leaks, pinpoint thermal bridges, discover structural defects, identify overheated connections or assess mould damage. The testo 871 thermal imager is ideal for applications in daily maintenance and installation work in trade and industry. Quick, simple and reliable for maintenance and detection of defects.
 

Technical highlights of the testo 871 thermal imager

Really simple operation with impressive professional thermal imaging technology: the testo 871 thermal imager has the following impressive features:

  • Detecting temperature differences from 0.09°C
  • The testo Thermography App enables you to write reports on site, save them online and send them by e-mail, as well as allowing you to use mobile terminal devices as a second display or for remote control
  • Wireless communication thanks to Bluetooth – this means you can also wirelessly integrate the readings of the compatible testo 770-3 clamp meter and testo 605i thermohygrometer
  • Built-in digital camera generates a real image in parallel to the thermal image
  • Critical temperature conditions are directly displayed via automatic hot-cold spot recognition
  • The testo ScaleAssist automatically ensures optimum setting of the thermal image scale, which means you generate objectively comparable and error-free thermal images, for example of the thermal insulation behaviour of buildings
  • The testo ɛ-Assist ensures the correct measurement result by automatically determining and setting the emissivity and reflected temperature
  • 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

Podrobno svetovanje na polju energije

V gradbeni termografiji je infrardeča tehnologija popolna za hitro in učinkovito analizo izgub energije v ogrevanju ali klimatiziranju stavb. Zahvaljujoč visoki temperaturni ločljivosti, termovizijska naprava ponuja podrobne slike neadekvatne izolacije in toplotnih mostov. Impresivna je glede beleženja in dokumentiranja izgub energije na zunanjih oknih ter vratih, ohišjih na roletah, nišah radiatorja, strešnih konstrukcijah ali celem okviru konstrukcije. Termovizijska naprava je najboljši merilni instrument za vseobsežno uporabo v diagnostiki in vzdrževanju ter zmeraj dobra izbira, ko gre za energetsko svetovanje.

Podpora preventivnemu vzdrževanju

Zanesljivo zgodnje odkrivanje poškodb na proizvodnih sistemih je ključno, da bi bila zagotovljena varnost in zanesljivost sistema ter se preprečili dragi zastoji v delu. Problematična področja v električnih in mehaničnih proizvodnih pogonih ponavadi postanejo očitna zaradi povečanja temperature prizadetih komponent. S pomočjo termovizijske naprave lahko direktno odkrijete kritične toplotne pogoje (znane kot vroče točke) v vašem sistemu, kar garantira dodatni bonus glede zanesljivosti. Tipične uporabe termovizijske naprave:
 
     Hitra lokacija vročih mest v električnih instalacijah
    Odkrivanje kritičnih toplotnih pogojev v motorjih, oseh in ležajih
 

 

Enostavno preverjanje ogrevalnega sistema in instalacij

Sistemi ogrevanja, ventilacije in klime se lahko hitro in zanesljivo preverijo zahvaljujoč enostavnem in intuitivnem delu Testo termovizijske naprave. 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:
 
 
     Določanje poteka zank za ogrevanje v sistemu talnega ogrevanja
    Preverjanje usedlin v radiatorjih
    Merjenje temperature pretoka in vračanja
 

 

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.

Testing the air tightness of new builds

Če vrata ali okna niso pravilno postavljena, pozimi lahko noter pride mrzel zrak ali topli notranji zrak lahko gre ven iz prostora. Rezultat tega je prepih, povečana izguba toplote in predvsem veliki stroški v odnosu na porabo energije. Kombinacija termografije in Blower Door se je zares pokazala vredna. Ta postopek vključuje nastajanje negativnega tlaka v stavbi, tako da mrzel zunanji zrak lahko v notranjost stavbe pride skozi prepustne povezave in razpoke. Testo termovizijska naprava olajšuje odkrivanje prepiha. Zaznavanje uhajanja kakršne koli vrste - preden obloge in okovi za novogradnjo popravilo naredijo zapletenim in dragim.
