This accessory set from Chauvin Arnoux consists of a shock-resistant protective sleeve and a Multifix magnetic holder, specifically designed for devices from the Physics Line. It serves as protection and mounting solution for measuring instruments such as the luxmeter C.A 1110, the climate meter C.A 1227, the humidity meter C.A 1246, the temperature measuring device C.A 1550, as well as the models C.A 1821, C.A 1822, and C.A 1823. The yellow protective sleeve provides additional shock protection for the device housing, reducing mechanical stress during operation. The Multifix magnetic holder enables flexible mounting on metallic surfaces or on a belt thanks to the V-shape of the holder design, facilitating practical use in various working environments.

Applications
This accessory set is designed for use in environmental and climate measurement applications, where devices are frequently moved or used in harsh environments. The protective sleeve shields the devices from mechanical impacts such as shocks or drops, while the magnetic holder allows for secure and quick mounting on metallic surfaces, such as machines or vehicles. The V-shape of the holder also enables attachment to belts, supporting hands-free use in the field.

Functions and Equipment in Detail
The yellow protective sleeve is specifically designed for the housings of Physics Line devices and conforms to their shape. It serves as mechanical protection and reduces the risk of damage from shocks or drops. The Multifix magnetic holder features a strong permanent magnet, ensuring secure attachment to metallic surfaces. The V-shaped design allows for convenient mounting on belts or other narrow carrying elements, keeping the device within easy reach during work.

Technology Explained Simply
The protective sleeve is made from a shock-absorbing material that absorbs impact energy, thereby protecting the sensitive measuring device. The Multifix holder uses magnetic attraction to securely fix the device to metallic surfaces without requiring additional fastening means such as screws or adhesives. The V-shape of the holder is ergonomically designed to keep the device stable even during movement.

Compatibility and Accessories
The accessory set is compatible with the following Chauvin Arnoux Physics Line devices: luxmeter C.A 1110, climate meter C.A 1227, humidity meter C.A 1246, temperature measuring device C.A 1550, as well as models C.A 1821, C.A 1822, and C.A 1823. The protective sleeve is included in the delivery scope of the Multifix adapter, so both components are supplied together. This is a set specifically developed for the mentioned devices and supports their functionality in operation.

Installation and Mounting
Installation is performed by simply inserting the device into the yellow protective sleeve and then attaching the Multifix magnetic holder to the back of the device. The holder is mounted on metallic surfaces or on a belt, with the V-shape ensuring secure anchoring. No additional tools or mounting aids are required. The mounting is quick and can be removed at any time.

Advantages in Operation
The combination of protective sleeve and Multifix holder increases the safety and practicality of the devices in use. The protective sleeve extends the service life of the measuring instruments through mechanical protection, while the holder simplifies handling in the field. Devices can be quickly and securely positioned without the user having to take their hands away from work. Compatibility with multiple models from the Physics Line makes the set universally applicable for various measurement tasks in environmental and climate applications.
