Chauvin Arnoux P01651011 CA 1510 test device for room air quality (white) content_copy

The Chauvin Arnoux CA 1510 is a portable room air quality meter for monitoring indoor air quality. It simultaneously measures the CO2 concentration, temperature, and relative humidity, enabling a comprehensive overview of room air conditions. The device is designed for both stationary and mobile applications and is particularly suitable for areas requiring continuous air quality control, such as schools, offices, hospitals, or public transport. Elevated CO2 concentration serves as an indicator of insufficient fresh air supply and may suggest high occupancy or inefficient ventilation.

Applications

The CA 1510 is used in various indoor environments where air quality monitoring is required. These include public facilities, commercial and office buildings, as well as private spaces. Measuring CO2 concentration supports the assessment of ventilation efficiency and can be helpful in preventing aerosol transmission, for example, in connection with the Covid-19 pandemic. Simultaneous recording of temperature and humidity enables a more comprehensive analysis of indoor climate conditions, which are relevant for user comfort and health.

Functions and Equipment in Detail

The device features a visual and audible alarm function, activated when predefined thresholds are exceeded. By default, an optical alarm with dual-color backlighting and pictograms, along with an audible tone, is triggered when CO2 concentration reaches 1000 ppm (medium restriction) or 1700 ppm (high restriction). Alarm thresholds can be adjusted by the user, for example, to 800 ppm. Additionally, the device offers a 3D mode, which displays the optimal comfort zone based on hygrometric criteria and CO2 concentration. The display can show values in °C or °F, and includes backlighting and a Hold function to retain the current measurement value. Minimum and maximum values for the measured parameters can also be displayed.

Technology Explained Simply

The CA 1510 measures CO2 concentration in the range of 0 to 5000 ppm with an accuracy of ± 50 ppm ± 3 % of the measured value and a resolution of 1 ppm. Temperature is measured in the range of -10 °C to 60 °C with an accuracy of ± 0.5 °C, and relative humidity in the range of 5 % to 95 % with an accuracy of ± 2 %. Measurement values are stored in an internal memory capable of holding up to 1 million data points. Recording can be done manually (M_REC) or programmed (P_REC), with start and end times, as well as recording frequency, set via PC software or Android app. In recording mode, the display can be locked to prevent showing measurement values.

Compatibility and Accessories

The device offers two communication modes: a wireless Bluetooth connection and a USB connection, where the device is recognized as a USB stick to enable easy data transfer. The included PC software and Android app allow graphical representation of measurement values, tabular evaluation, data export, and report generation. Available accessories include a white wall mount, a black wall mount, a USB power adapter, a transport case, and a Bluetooth / USB modem for PC.

Mounting and Installation

The CA 1510 can be mounted in various ways: using a magnet, via a wall mounting system, through a slot for hanging, or in a table stand (included with the CA 1510W). The table stand allows stable positioning on a surface, while magnet and wall mounting are suitable for permanent installation on walls or metallic surfaces.

Operational Advantages

The device is designed for long-term operation using batteries. With two 1.5V LR6 batteries or rechargeable batteries, it can measure every 10 minutes in ECO mode, enabling an autonomy of up to one year. Power supply is also possible via a power adapter or Micro-USB. The integrated software enables detailed analysis of measurement data, allowing ventilation system efficiency to be checked and optimized. User-friendliness is enhanced by the clear display and simple operation, enabling direct reading of measurement values on the device or analysis via software. Batteries are not included in the delivery scope.
