You can detect possible structural defects with the testo 875-1i thermal imager in building thermography. With the excellent thermal sensitivity of < 50 mK, you can quickly and efficiently track down energy losses and so help your customers to save expensive heating costs and plan refurbishments.

In the “Applications” tab, you can find out more about the thermal imager's fields of application.

The testo 875-1i Infrared Imaging Camera’s technical features
The testo 875-1i thermal imager is characterised by its intuitive operation, excellent thermal sensitivity and built-in digital camera. Read all the important information here:

-  Built-in digital camera: Recording real images in parallel to each thermal image makes documentation and assignment easier

-  Resolution and image quality: Detector size 160 × 120 pixels = 19,200 temperature measuring points.

-  *SuperResolution Technology (optional) enables you to take image quality right up to the next level of 320 × 240 pixels in next to no time. Four times as many readings and a geometric resolution that has been improved by a factor of 1.6 mean you get even more detail and even greater reliability with thermographic measurements

-  Thermal sensitivity < 50 mK: Thanks to a temperature resolution of < 50 mK, even the smallest temperature differences can be seen

-  High-quality 32° × 23° lens: The lens with its manual focusing enables a wide field of view and an ideal overview of the temperature distribution, along with precise focusing on the object being measured

-  Automatic hot/cold spot detection: Critical temperature conditions are directly displayed during thermography

-  Solar mode: The solar radiation value can be input into the thermal imager and stored with each thermal image

-  Pro software for image evaluation on the PC included. You can also choose to save the thermal images as JPEGs. Find out more about the software Link to the “testo IRSoft” pdf

-  Measuring range: -30 to +350 °C

Easy monitoring of heating and installation systems

Testo thermal imagers are easy and intuitive to operate, so they are ideal for quickly and reliably checking heating, ventilation and air conditioning systems. A quick glance with the thermal imager is enough to discover irregularities in the temperature distribution. Thus, thermography can be used to easily locate clogged radiators and leaks.

Typical applications for the thermal imager:

 

  • Pinpointing the course of heating loops in an underfloor heating system
  • Checking radiators for the build-up of deposits
  • Measuring the supply and return temperature
  • Locating leaks

 

Preventive maintenance

Ideal for the early identification of imminent malfunctions or defects on plants and machines: Reliably record temperature increases with a thermal imager.

  • Fast detection of critical thermal status (so-called HotSpots) during continuing operation
  • Avoid expensive damage, downtimes and fire risks on plants and machines
Electrical maintenance
  • Test switching cabinets, electrical conditions, photovoltaic plants
  • Evaluate heat status in low, medium and high voltage plants
Mechanical maintenance
  • Identify wear on machines
  • Test motors, bearings, shafts

    Detecting structural defects and ensuring construction quality

    • Detect potential building defects, prove quality and the implementation of construction measures without contact – with the help of thermal images
    • Test air-tightness of windows and doors
    • Locate insulation errors and cold bridges in a building shell
    • Detect and visualize mould-risk areas

    Easy checking of heating systems and installations

    • test heating and air conditioning/ventilation systems: Use a thermal imager to identify irregularities in the temperature distribution quickly and easily
    • Localization of the course of heating loops in underfloor heating systems
    • Testo radiators for silting
    • Measure flow and return temperatures

    Localize pipe ruptures

    • Reliably determine pipe ruptures with the help of a thermal imager – without unnecessarily opening walls and floors
    • Precise localization of leakages in underfloor heating and other inaccessible pipe systems

    Locating leaks in flat roofs

    • Detection of damp in roofs: Based on temperature differences (such as occur mainly in flat roofs), thermal imagers show areas on the roof with sealed-in moisture or damaged insulation

    More reliability in quality assurance and production monitoring

    • A Testo thermal imager supports in process control and product quality asurance
    • Identify foreign bodies in production processes and anomalies in the heat distribution of components quickly and without contact
    • Fast and easy monitoring of filling level in closed liquid tanks

    Research and development

    • Identify thermal anomalies and monitor cooling and heating processes in real time
    • Precisely visualize critical temperatures on circuit boards: Thanks to the finest geometric resolution of the high-quality Testo thermal imagers
    • Analyze heat occurrence and conduction in circuit boards, and optimize development processes: The process analysis package offers practical features such as video recording and image sequence storage for easy analysis of thermal processes
