The Didactic Kit C.A 1875 from Chauvin Arnoux is a tool specifically developed for use in training, designed to demonstrate and analyze the most common error sources when using thermal imaging cameras. It serves as a practical learning environment to understand the physical fundamentals of thermography and to recognize the effects of various parameters on measurement accuracy. The set enables experimental verification of the influence of surface properties, positioning, reflection, transmission, and spatial resolution on temperature measurement.

Applications
This kit is primarily designed for training, education, and further education in the field of thermography. It is suitable for demonstrating physical principles involved in the use of thermal imaging cameras, as well as for conveying knowledge on avoiding typical measurement errors. Its practical design supports understanding how to optimize thermal analyses in technical and industrial applications.

Functions and Equipment in Detail
The set includes a heatable thermal plate serving as a radiation source, as well as several surface plates made of different materials. These plates are used to visualize the influence of emissivity—the ability of a surface to emit heat—on temperature measurement. The materials differ in surface texture and material properties, which causes variations in measurement results at the same temperature. Additionally, shielding elements with magnetic mounting are included, which can be flexibly attached to the kit to enable targeted experiments.

Explaining Technology in an Understandable Way
Spatial resolution is illustrated by recognizing minimal temperature measurement areas depending on the distance to the target. This demonstrates how the size of the measurement area and the distance to the radiation source affect measurement accuracy. The influence of positioning is demonstrated by visualizing the camera’s positioning relative to the target, making the angle of incidence and its impact on measurement results visible. The functions for displaying reflection and transmission enable understanding of phenomena such as reflections or material transparency, which can lead to measurement errors in thermography.

Compatibility and Accessories
The device is designed independently of specific thermal imaging cameras and can be used with various devices to demonstrate the described effects. The integrated manual, including practical examples and theoretical explanations, supports the learning process and provides structured experiment instructions. Power supply is via 230 V –; 50 / 60 Hz, enabling use in standard electrical outlets.

Mounting and Installation
The shielding elements are attached to the kit using magnets, allowing for quick and flexible adjustment of the experimental setup. The thermal plate is directly integrated into the kit and can be activated via the power supply. No additional mounting or installation work is required; the device is ready for immediate use.

Operational Advantages
The kit provides a clear, visual representation of the most important error sources in thermography. The experimental approach promotes a deeper understanding of the physical relationships. The combination of practical experiments and theoretical explanations in the manual supports long-term learning effects. The modular design with interchangeable plates enables a wide range of experiments and adaptations to different teaching content.
