Air quality measuring device for orienting measurement of the environmental conditions / Determination of HCHO, fine dust (PM2.5 / PM10) / Temperature and relative humidity / 3 "TFT LCD display
The air quality meter from PCE Instruments is a true all-rounder when it comes to indoor air quality assessment. The air quality measuring device quickly and accurately determines several environmental parameters that are of crucial importance for health and well-being. The air quality measuring device enables effective and uncomplicated measurement of volatile organic compounds (TVOC), fine dust (PM2.5 / PM10), temperature, formaldehyde (HCHO), and relative humidity. The display also has a date display with time specifications.
The room air contaminated by volatile organic compounds can, among other things, lead to headaches, tiredness, or respiratory irritation. According to one study, people in Europe spend about 90% of their time indoors. In such cases, between 10 and 20 cubic meters of air per person are inhaled, which corresponds to an air mass of 12 to 24 kg, considerably more than a daily consumption of food and liquid. Air quality is, therefore, a very important factor in terms of health and well-being.
The quality of indoor air should therefore be checked regularly. This is particularly convenient with the color rating scale of the air quality meter from PCE Instruments. The colored scale serves as an indicator that simplifies the user's orientation and the classification of the displayed measured values: as soon as a limit value is exceeded, this is shown in color on display. In addition, if desired, in case of potential danger, the air quality meter also makes an acoustic signal. This function is useful, for example, when measuring the pollutant substances in the indoor air. The air quality meter from PCE Instruments, for example, makes it possible to effectively detect the fine dust load. Here, a distinction is made between fine dust particles with a maximum diameter of up to 10 μm (PM10) and fine dust particles with a diameter of up to 2.5 μm (PM2.5). In addition, the air quality meter precisely indicates the formaldehyde concentration in the room air. For the measurement of volatile organic compounds (TVOD), the fine dust meter has a measuring range of 0 to 9.99 mg / m³. The manufacturer has also equipped the air quality meter with a large memory for 5000 measuring groups so that the determined values could also be retrieved later. In addition, the air quality meter provides reliable information about the temperature (-20° C to +70° C) and humidity (0 to 100% RH). The measured values are updated on display every second.
The easy-to-read display of the air quality gauge shows the measured values alternately. The user also has the opportunity to use the device for a while, completely self-sufficient, without any connection to a power source. After five hours of continuous operation, the air quality meter must be recharged via the batteries. It takes two hours for the battery of the device to be fully charged again. In order to provide a continuous measurement of the environmental conditions, the manufacturer has equipped the air quality meter with a USB port. In this way, the user can connect the fine dust meter to a power source and, thus, charge it or operate it via the mains. If required, the air quality meter can also be put into automatic sleep mode. The PM2.5, PM10, and CO2 sensors then need a warm-up time of about 5 seconds, and the TVOC sensor - 40 seconds to provide accurate readings. Through a built-in noise sensor, the air quality meter turns on automatically when a noise activates the sensor in the device. If desired, this sensor can also be deactivated by the user.
