Technology
The Polludrone Lite air quality monitor works on proven working principles like NDIR, Electrochemical Analysis, Semiconductor, Optical Measurement, and Laser-Scattering. As a part of our proprietary ‘Micro Active Sampling’ (e-breathing technology), we have a sophisticated suction-and-exhaust system for air sample collection and monitoring inside a controlled environment. This isolates the effect of the external environment on measurement to achieve 13% higher accuracy than the industry standards.
Laser Scattering – The sensor emits a laser beam to diffract through the air sample collected in the equipment. The intensity of the beam scattered from the particles provides particle size distribution and concentration data.
Electrochemical Analysis – The gaseous emission is treated electrochemically, where an external potential is applied. Hence, each species like CO2, H2S, CH4, etc. is identifiable depending on their oxidation or reduction potential.
NDIR – The gaseous emission from the location undergoes Nondispersive Infrared Radiation where the air sample comes in contact with infrared radiation. Different gaseous molecules absorb IR at different frequencies. So, the amount of IR absorbed gives the volumetric concentration of each gaseous constituent.
