This data logger measures and stores relative humidity, temperature and carbon dioxide concentration readings. You can easily set up logging parameters and download recorded data into PC's USB port.
It has a large LCD display with a backlight.

This device measures the content of PM2.5 and PM10 dust particles in the air.

PM10 dust is a mixture of airborne particles with a diameter of less than 10 micrometers. These particles can reach the upper respiratory tract and lungs. The acceptable average daily concentration for PM10 dust is 50 µg / m3.

PM2.5 dust contains particles smaller than 2.5 micrometers in diameter. These particles, in addition to penetrating the upper and lower respiratory tract, can also enter the blood. The acceptable average daily concentration for PM2.5 dust is 25 µg / m3.

The meter is equipped with a laser detector that counts suspended dust particles. Measurement takes 50 seconds. After its completion, the result is presented in numerical and graphic form on a colored air quality scale.

This small, portable meter measures the content of PM2.5 dust particles in the air and shows the current concentration of PM2.5 suspended dust on a clear LCD display.

PM2.5 dust contains particles smaller than 2.5 micrometers in diameter. These particles, in addition to penetrating the upper and lower respiratory tract, can also enter the blood. The acceptable average daily concentration for PM2.5 dust is 25 µg / m3.
