Applications
Detecting structural defects and ensuring construction quality (especially: air tightness of windows and doors)
Analysis with a Testo thermal imager is a fast and efficient method of detecting possible structural defects. Furthermore, Testo thermal imagers are ideally suited for providing proof of the quality and correct implementation of construction measures. Any heat losses, humidity and lack of air tightness in a building are visible in the thermal image. The Testo thermal imager makes it possible to detect faulty thermal insulation and structural damage – all using a non-contact method! The testo ScaleAssist function, which automatically ensures optimum setting of the thermal image scale, means you get objectively comparable thermal images of buildings. This makes correct assessment of structural defects and thermal bridges easier than ever before. Checking the air tightness of windows and doors is one of the typical applications of the thermal imager.
Easy checking 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. Just a quick look with the thermal imager is enough to discover irregularities in temperature distribution. Thus, thermography can be used to easily locate clogged radiators and leaks. Typical applications for the thermal imager:
-
Checking radiators for silting
-
Locating leaks
-
Measuring the flow and return temperature
-
Pinpointing the course of heating loops in an underfloor heating system
Support in preventive maintenance
Reliable early detection of damage to production-relevant systems is essential in order to guarantee the safety and reliability of the system and prevent costly downtimes. Problematic areas in electrical and mechanical production facilities usually become evident due to an increase in temperature of the affected components. You can use a thermal imager to detect critical heat conditions (known as hotspots) in your system directly during operation, therefore guaranteeing an additional bonus in terms of reliability. Typical applications for the thermal imager:
-
Quick location of hotspots in electrical installations
-
Detection of critical heat conditions in engines, shafts and bearings
