Chauvin Arnoux CA 1954 DiaCAM2 thermal imaging camera content_copy

The CA 1954 thermal imaging camera from Chauvin Arnoux is a compact measuring instrument for thermographic applications in building technology, electrical and mechanical maintenance. It enables the visual representation of temperature distributions and supports early detection of anomalies such as overheating, thermal bridges or damp areas. The device is designed for easy operation and offers direct access to all functions with one hand. The integrated handle ensures stable placement on flat surfaces, facilitating fieldwork.

Applications
The CA 1954 is suitable for a wide range of applications. In building thermography, it is used for conducting energy efficiency audits to identify air leaks, thermal bridges or damp areas. In electrical maintenance, it helps locate defective contacts, load asymmetries or undersized components. In mechanical maintenance, it aids in detecting wear points, motor overheating or lubrication issues. Thus, the camera is a universal tool for preventive maintenance.

Functions and Equipment in Detail
The device features a 2.8-inch display with automatic brightness adjustment, enabling the display of thermal images and real images. The display uses multiple color palettes, making temperature differences visually clear. The camera offers a wide-angle field of view of 38° x 28°, which operates without focusing – the image remains sharp at any distance without manual adjustment. The minimum focusing distance is 30 cm. The integrated lens cover protects the lens from scratches and is non-removable.

Technology Explained Simply
The sensor is based on a UFPA microbolometer with a resolution of 160 x 120 pixels in the spectral range of 8 to 14 µm. The thermal sensitivity (NETD) is 80 mK at 30 °C, enabling accurate representation of temperature differences. The temperature measurement range is between -20 °C and +250 °C, with an accuracy of ±2 °C or ±2 % of the reading. The spatial resolution (IFOV) is 4.1 mrad. The camera captures real images with a resolution of 320 x 240 pixels and offers automatic parallax correction, ensuring thermal image and photo image align spatially. Image fusion via PC software is also possible.

Compatibility and Accessories
The CA 1954 can receive data via Bluetooth from other measuring instruments, including current clamps (e.g. CA 1821/22/23, F407, F607), multimeters (e.g. CA 1246, CA 1227) and environmental measuring devices (e.g. MTX 3292, MTX 3293). The transferred data includes current, ambient temperature, relative humidity and dew point. The camera is equipped with an integrated Bluetooth headset, allowing voice comments to be recorded directly onto the image. Data is stored on a removable micro SD card, which has a standard capacity of 2 GB (approx. 4000 images) and is expandable up to 32 GB. Images are available in .bmp or .png format (when recording both thermal and real image simultaneously).

Mounting and Installation
The camera can be mounted on a tripod using a ¼'' tripod thread insert. The drop resistance is 2 meters from all sides, increasing operational safety. The IP 54 protection rating safeguards against dust and splashing water, allowing use outdoors. The charger is included in the delivery scope; charging is performed externally. Typical autonomy is 9 hours at 50 % brightness and disabled Bluetooth.

Operational Advantages
The camera offers programmable acoustic and visual alarms, activated when minimum and maximum thresholds are exceeded. Context-sensitive help supports the user during operation and minimizes errors. The integrated emissivity table is expandable, allowing specific materials to be considered. The CAmReport software enables detailed analysis of thermograms, including temperature display at each pixel, heat profile, area analysis and automatic report generation in PDF or Word format. Reports can be created and exported directly via the software, simplifying documentation and archiving. The camera is developed and manufactured in France.
