The C.A 895 gas detector from Chauvin Arnoux is a portable measuring instrument for the detection and quantification of carbon monoxide (CO) in ambient air. It belongs to the Physics Line product series and is specifically designed for mobile applications where rapid and reliable detection of CO concentrations is required. The device features a compact, shock-protected housing, enabling mobile use under various conditions. The CO concentration is displayed digitally, providing the user with immediate information on the current value.

Applications
The C.A 895 is particularly suitable for locating CO sources indoors, for example in residential buildings, commercial premises, or during inspection of heating systems. The acoustic hazard warning, operating on the principle of a Geiger counter, alerts the user to rising CO levels with a pulsating signal. A continuous tone sounds at a concentration of 200 ppm, indicating a potentially hazardous situation. This function supports rapid response to elevated CO levels and is especially useful during inspections or safety checks.

Functions and Equipment in Detail
The device offers two measurement modes: In the normal mode, the CO concentration is displayed in real time, allowing sources to be quickly localized. The average mode is used to generate stable, averaged measurement values, suitable for precise monitoring and documentation. Additional functions include the HOLD function, which locks the current measurement value, and the storage of the maximum value reached during measurement. These functions facilitate analysis and documentation of measured values.

Technology Explained Simply
The measurement range of the C.A 895 is between 0 and 1000 ppm (parts per million), equivalent to 0 to 1000 parts per million of air volume. Accuracy is ± 5 % of the scale value plus ± 5 ppm, enabling reliable measurement even at low concentrations. The acoustic warning function responds sensitively to increasing CO levels, with the signal tone frequency increasing as the concentration rises.

Compatibility and Accessories
The device is supplied with a shock-protective case and an operating manual. The shock-protective case protects the device during transport and field use. The operating manual contains necessary information for commissioning, operation, and maintenance.

Mounting and Installation
The C.A 895 is designed as a portable device and requires no mounting or installation. It is held directly in hand or transported in the shock-protective case. Operation is performed via buttons on the device, controlling various functions such as HOLD, maximum value storage, and measurement mode switching.

Operational Advantages
Thanks to its small dimensions of 237 x 60.5 x 38 mm and a weight of 190 g, the device is lightweight and easy to handle. The combination of two measurement modes, acoustic warning, and storage functions makes it an efficient tool for technical inspections and safety checks. The direct display of CO concentration enables quick decision-making during use.

Scope of Delivery
The scope of delivery includes the C.A 895 gas detector, a shock-protective case, and the operating manual.
