Testo’s new thermal imagers for HVAC professionals

Testo introduces an updated line of thermal imagers designed to
simplify work for HVAC professionals.

The new thermal imagers, the 865, 868, 871 and 872, are full-featured devices
designed to assist users with preventative maintenance of HVAC systems through
early detection of problems, as well as identification of structural defects in
buildings that could compromise system performance.

Preventative maintenance of HVAC

HVAC technicians are tasked with identifying potential issues in heating
and cooling systems before they can evolve into serious concerns. Early
detection of defects or damage will not only save money on maintenance down the
line, but will also ensure the system is safe for the customer.

Testo’s thermal imagers can easily detect hotspots or critical heat
conditions in the system that will eventually cause problems. Hotspots usually
occur in the electrical components of the HVAC system or in the engine’s shafts
and bearings that drive it; identifying these hotspots quickly enables technicians
to address the problem before damage is caused.

Mould growth due to the formation of condensation inside the machinery, is
another common issue that can affect the performance of HVAC systems. This will
not only damage the inner workings of a unit, but can also present serious
health risks. Testo’s thermal imagers can calculate the surface moisture value
for measuring points, allowing users to pre-emptively identify mould
growth before it actually manifests itself.

Structural defects

The performance of HVAC systems can be impacted by structural defects in
a building, which can potentially cause heat loss, excess humidity and lack of
air tightness. Testo’s thermal imagers can help identify such defects by
revealing the sources, indicating faults with thermal insulation or

Even if these issues do not warrant any major repairs or construction
work, the seemingly minor faults can have an impact on the energy efficiency of
the building, especially affecting heating and air conditioning systems. Early
detection of such problems can halt further damage in its tracks, and ensure
the structure isn’t suffering from poor insulation.
