Product Description

The testo 872 thermal imager is ideally suited for professional industrial and building thermography - at the same time it ensures your work is both quick and easy. It is versatile to use, for example in industrial and mechanical maintenance or for detecting structural defects. 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 thermal image scale.
 

The testo 872 thermal imager– smart and networked

The testo 872 thermal imager guarantees wireless communication with mobile terminal devices via WLAN. 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 872 delivers even more informative thermal images in combination with the compatible 770-3 clamp meter and testo 605i thermohygrometer. Both are available separately – simply order them straight away along with your testo 872. The thermal imager wirelessly integrates the measurement results of these measuring instruments 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 humidity measuring instrument 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 872 thermal imager

Detect locations at risk of developing mould, pinpoint thermal bridges, discover structural defects or identify overheated connections. The testo 872 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 872 thermal imager

The testo 872 thermal imager is characterized by its easy handling and its outstanding image quality. Its technical features are impressive:

  • Detecting temperature differences from as little as 0.06°C
  • testo Thermography App to use mobile terminal devices as a second display and for remote control or to write and send reports, along with saving them online
  • 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 and laser marker generate 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

Detaljno savjetovanje na polju energije

U građevinskoj termografiji, infracrvena tehnologija idealna je za brzu i učinkovitu analizu gubitaka energije u grijanju ili klimatizaciji zgrada. Zahvaljujući visokoj temperaturnoj razlučivosti, termovizijski uređaj pruža detaljne slike neadekvatne izolacije i toplinskih mostova. Impresivan je u pogledu bilježenja i dokumentiranja gubitaka energije na vanjskim prozorima i vratima, kućištima na roletama, nišama radijatora, krovnim konstrukcijama ili cijelom okviru konstrukcije. Termovizijski uređaj najbolji je mjerni instrument za sveobuhvatnu upotrebu u dijagnostici i održavanju i uvijek dobar izbor kada je u pitanju energetsko savjetovanje.

Support in preventive maintenance

Pouzdano rano otkrivanje oštećenja na proizvodnim sustavima ključno je kako bi se zajamčila sigurnost i pouzdanost sustava i spriječili skupi zastoji u radu. Problematična područja u električnim i mehaničkim proizvodnim pogonima obično postaju očita zbog povećanja temperature pogođenih komponenti. Pomoću termovizijskog uređaja možete izravno otkrivati kritične toplinske uvjete (poznate kao vruće točke) u vašem sustavu, što jamči dodatni bonus u pogledu pouzdanosti. Tipične primjene termovizijskog uređaja:
 
Brza lokacija vrućih mjesta u električnim instalacijama
Otkrivanje kritičnih toplinskih uvjeta u motorima, osovinama i ležajevima
 

 

Jednostavna provjera sustava grijanja i instalacija

Sustavi grijanja, ventilacije i klimatizacije mogu se brzo i pouzdano provjeriti zahvaljujući laganom i intuitivnom radu Testo termovizijskog uređaja. Dovoljna je brza primjena termovizijskog uređaja kako biste otkrili nepravilnosti u raspodjeli temperature. Tako se termografija može koristiti za jednostavno lociranje začepljenih radijatora i curenja.
 
Tipične primjene termovizijskog uređaja:
 
 
     Određivanje tijeka petlji za grijanje u sustavu podnog grijanja
    Provjera taloga u radijatorima
    Mjerenje temperature protoka i povrata
 

 

Na tragu puknute cijevi

Ako se sumnja na puknuće cijevi, jedino preostalo rješenje je otvoriti cijela područja zida ili poda. Termovizijski uređaj omogućuje vam da umanjite štetu i smanjite troškove jer precizno locirate curenja u podnom grijanju i drugim nepristupačnim cjevovodima. Na taj se način izbjegava nepotrebno otvaranje zidova i podova i znatno se smanjuju troškovi popravka.

Testing the air tightness of new builds

Ako vrata ili prozori nisu pravilno postavljeni, zimi može ući hladan zrak ili topli unutarnji zrak može izaći iz prostorije. To rezultira propuhom, povećanim gubitkom topline i nadasve velikim troškovima u odnosu na potrošnju energije. Kombinacija termografije i Blower Door doista se pokazala vrijednom. Ovaj postupak uključuje stvaranje negativnog tlaka u zgradi, tako da hladan vanjski zrak može procuriti u unutrašnjost zgrade kroz propusne spojeve i pukotine. Testo termovizijski uređaj olakšava otkrivanje propuha. Detekcija curenja bilo koje vrste – prije nego obloge i okovi za novogradnju učine popravak kompliciranim i skupim.
