GRIMM Model 1.129 Sky-OPC Aerosol Spectrometer
Brand: DuragThe Aerosol spectrometer model 1.129 Sky-OPC is specifically designed for air-borne measurements at different altitudes.
The sample flow rate, maintained by an external vacuum pump, is controlled by a critical orifice.
The instrument detects aerosol particles in real time in the size range 0.25 to 32 µm in 31 size channels and displays the results as particle concentration or optionally as particle mass.
Features- Real time measurements of aerosol particles and droplets
- Sample flow independent on atmospheric pressure
- 31 size channels within 6 Second
- Fast scanning down to 1 Second
- Particle concentration, dust mass (or PM-values optional)
- Optional pressure, humidity and temperature sensors
- Easy to install and maintain due to docking station
- Data logging on storage card or online via PC
