Thermal imaging cameras:
Making temperature distributions visible

This section covers the key basics that are essential for understandable and reproducible thermography.

• How thermal imaging cameras measure (surface, not "through walls")

• Which parameters influence measured values (e.g. emissivity and reflected temperature)

• How object size, distance, and IFOV cause or avoid typical measurement errors

This section classifies typical use cases and shows what matters in practice for each application.

• Building thermography (thermal bridges, leaks, mould risk)

• Electrical inspection (switch cabinets, connections, load)

• Maintenance, HVAC/R, and photovoltaics

This section covers the technical basics and key figures that are truly relevant to the measurement task.

• Resolution, NETD, focus, and field of view (FOV)

• Optics/lenses and their influence on measurement capability

• Software, app, and reporting for recurring inspections

This section provides a structured selection logic: from the measurement task to the right device and workflow.

• Which camera suits the object size and measuring distance (IFOV as a gate)

• Which functions improve comparability (scale, focus, reporting)

• How to combine requirements from application and technology

This section brings together practical resources such as guides, pocket guides, application examples, and references.

• Practical guides by application

• Thermography pocket guide

• Application examples and references (e.g. related to the testo 883)
