iP2 is a high precise instrument mainly used to measure the fine particles PM2.5 using the laser technology. iP2 can continuously display the ambient concentration of fine particles in micrograms per cubic meter of air (µg/m3).  

• Detect atmospheric PM2.5 with laser scattering theory
• High-precision detection, rapid response and operation
• Particulate measurement range: 0.3 ~ 2.5 μm
• Six sides shield, superior anti-interference performance
• Only one power button and easy to operate
• Two AAA Alkaline Batteries
