Ambient Air Sampler

Product Details:

With sincere intentions to preserve and uplift our reputation in the market, we bring forth a distinguished assortment of PM-10 Respirable Dust Sampler .  It uses an electronic flow controller to automatically maintain constant sampling rate through the filter/cyclone assembly. Our offered sampler is precisely manufactured using utmost-grade raw material and latest technology in conformity with defined quality standards. Tested against various quality parameters, this sampler is delivered at client's end without any hassle. 

Features:

• Rugged design
• Reliable operation
• Unmatched performance

Special Features:

• Automatic Flow Controller with electronic feedback for constant sampling rate throughout the sampling period.
• Brushless regenerative blower with very little noise.
• Heavy duty Induction motor fitted in blower requires no maintenance.
• Blower immune to voltage fluctuations thus eliminating need of voltage stabilizer.
• Electromagnetic interference (EMI) to TVs is totally eliminated.

Specifications:

• Flow Rate:Free flow (with flow stabilization disabled) > 1.3 m3 /min. 1.0 m3 /min with Filter Paper installed and Flow Controller enabled
• Flow Rate Control:The system will automatically maintain the flow rate constant and compensate for dust load deposited on the filter. When the dust load increases beyond the capacity of the blower the flow rate will begin to decrease and the system will automatically be shutdown if the flow rate tends to drop below 0.85 m3 /min
• Particle Size:Particles of 10 microns & below collected on Filter Paper holder. SPM bigger than 10 microns collected in a separate sampling bottle under the cyclone
• Sampling Time:24 hours (maximum)
• Sampling Time Record:0 to 9999.99 hrs. recorded on a Time Totalizer
• Power requirement:Nominal 220 V, Single Phase, 50Hz AC mains supply. For proper operation and safety a good earth connection is mandatory
• Size & Weight:400 x 300 x 650mm., 40Kg
• Automatic Sampling:24 hrs programmable timer to automatically shut off the system after pre-Control set time interval.
• Warranty:One year

Other Details:

• Ambient air enters the sampler through an omnidirectional inlet designed to provide a clear aerodynamic cut-point for particles larger than 10 microns.
• The air stream then passes through a WINS Impactor that retains the fraction between PM10 and PM2.5. The PM10 and PM2.5 impactors used are based on designs standardized by USEPA and as such the system complies with international norms for PM2.5 Samplers.
• The sampling rate is held constant at 1 m3/hr by a mass flow controller. An ambient air temperature sensor and barometric pressure sensor have been provided to automatically compensate for temperature and pressure while reporting flow rate in volumetric flow units.
• It has an in-built data logger that records air temperature, filter temperature, flow rate and also totalizes and records the volume of air sampled. A PC based software is provided to download the data for audit.

Special Features:

• PM 10 and PM 2.5 Impactors of sampler based on designs standardized by US EPA.
• Flow Control based on Mass Flow measurements to remove errors due to pressure, temperature changes (of both ambient air and filter).
• Auto shut off if flow rate drops significantly below 1 m3/hr.
• Microcontroller based datalogger records Air Temp., Filter Temp. and Flow rate.
• Windows based software for downloading data.
• Pump Assembly in separate cabinet to prevent loss of volatile fraction and improve portability.
• Special imported oil-free brushless vacuum pump that is practically noiseless.
