Kaiterra – Laser Egg 2+

General Description

The Kaiterra Laser Egg 2+ provides real-time measurements of PM_2.5 and PM₁₀ mass concentrations. The device also provides temperature, relative humidity, and TVOC measurements. Real-time data is displayed on the device’s screen. The Kaiterra mobile app also allows for viewing of real-time data, as well as retrieval of historical data.

Principle of Operation

The Kaiterra Laser Egg 2+ uses a laser particle counter, in which a sensor detects diffracted light from a particle crossing a laser beam. The diffraction events are grouped by light intensity, which are related to particle size, and a complex algorithm uses this information to calculate PM_2.5 and PM₁₀ mass in µg/m³. The sensors come factory calibrated.
