• Integrated 5 MP digital camera
• Integrated laser marker – also precisely visible as a measuring point in the thermal image
• Highest image quality thanks to high resolution: 76,800 temperature measuring points for precise thermography
• Detecting temperature differences from as little as 32.09°F (0.05°C)
• Wireless communication thanks to Bluetooth
• Built-in digital camera generate a real image in parallel to the thermal image
• Critical temperature conditions are directly displayed via automatic hot-cold spot recognition
• 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
• ε-Assist ensures the correct measurement result by automatically determining and setting the emissivity and reflected temperature
• IFOV warner - 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
• Laser marker for better orientation
• You can choose to save thermal images as JPEGs
• Pro software for image evaluation on the PC

ScaleAssist

Since the temperature scale and coloring of thermal images can be adapted individually, it is possible that the thermal behavior of a building, for example, can be wrongly interpreted. The ScaleAssist function solves this problem by adjusting the color distribution of the scale to the interior and exterior temperature of the measurement object and the difference between them. This ensures objectively comparable and error-free thermal images.

Applications

Detect locations at risk of developing mold, pinpoint thermal bridges, discover structural defects or identify overheated connections with this thermal imager. It is ideal for daily maintenance and installation work in trade and industry and offers quick, simple, and reliable maintenance and detection of defects.

Detecting structural defects and ensuring building quality

Analysis with this thermal imager is a fast and efficient method of detecting possible structural defects. Furthermore, this thermal imager is ideal for providing proof of the quality and correct implementation of construction measures. Any heat losses, humidity, and lack of air tightness arising in a building are visible in the thermal image. This thermal imager detects structural damage and implementation defects in the thermal insulation, all using a non-contact method! The ScaleAssist function, which automatically ensures optimum setting of the thermal image scale, means you get objectively comparable thermal images of buildings, making a correct assessment of structural defects and thermal bridges easier than ever before. Detecting insulation defects and thermal bridges in the building shell is one of the typical applications.

Carrying out detailed energy consultancy

In building thermography, infrared technology is ideal for the fast and effective analysis of energy losses in the heating or air conditioning in buildings. With its high-temperature resolution, this thermal imager provides detailed images of inadequate insulation and thermal bridges. It is impressive at recording and documenting energy losses on outer windows and doors, roller blind casings, radiator niches, roof constructions, or the entire building shell. This thermal imager is the best measuring instrument for comprehensive diagnostic and maintenance uses and is always a good choice for energy consultancy.

Support in preventive maintenance

Reliable early detection of damage to production-relevant systems is essential 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 the temperature of the affected components. You can use this 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 this thermal imager:

• Quick location of hotspots in electrical installations
• Detection of critical heat conditions in engines, shafts and bearings

Easy checking of heating systems and installations

Quickly and reliably check heating, ventilation, and air conditioning systems with the easy and intuitive operation. A quick look with this thermal imager is enough to discover irregularities in temperature distribution, meaning thermography can easily locate clogged radiators and leaks. Typical applications for this thermal imager:

• Pinpointing the course of heating loops in an underfloor heating system
• Checking radiators for silting
• Measuring the flow and return temperature

On the trail of a ruptured pipe

If a pipe rupture is suspected, the only solution left is often to break open entire wall or flooring areas. This thermal imager enables you to minimize damage and reduce costs, because you locate precise leaks in underfloor heating and other inaccessible pipelines. This avoids opening up walls and floors unnecessarily and considerably reduces the repair costs.

Preventing mould formation

Thermal bridges waste energy, and condensation can also form in these places due to humidity in the ambient air. As a result, mold develops in these areas with the associated health risks for the occupants. This thermal imager uses the ambient temperature and humidity, determined externally with the 605i smart probe (sold separately), along with the measured surface temperature to calculate the value of the relative surface moisture for each measuring point directly in the measuring instrument. Mold formation is therefore shown on the display before it becomes visible: areas at risk are displayed in red, those not at risk in green. This makes it possible to introduce measures to prevent dangerous mold formation in good time, including hidden corners and alcoves.

Testing the air tightness of new builds

If doors or windows are not fitted correctly, winter cold air can enter, or warm indoor air can escape, resulting in draughts, increased ventilation heat loss, and high energy costs. The combination of thermography and Blower Door has proved its worth. This procedure involves creating a negative pressure in the building so cool outside air can flow into the interior of the building through leaky joints and cracks. This thermal imager makes the detection of the leaks considerably easier here. Any leaks located before facings and fittings for the new build make repair work complicated and costly.
