The testo 890 is a handy and robust thermal imager. It enables you
to carry out contactless determination and display of the
temperature distribution on surfaces.
Typical areas of application are:
• Building inspection: energetic assessment of buildings, and
inspection of heating, ventilation and air conditioning systems.
• Preventative maintenance (servicing): mechanical and electrical
inspection of systems, machines and energy distribution
systems
• Production monitoring (quality assurance): monitoring of
production processes
• Professional energy consultation, leak detection
