The High Volume Sampler is meant for monitoring the Total Suspended Particles (TSP) in ambient air conditions. It also simultaneously used for sampling the pollutant gases like SO2, NOX, CL2 H2S, and CS2. These gases are analyzed to determine the concentration of specific pollutant.
Working : This high volume sampler separates the particles larger than 10 microns that are present in air stream. These coarse particles are separated before filtering the air on 0.5 micron size filter and allows the measurement of TSP and Respirable fraction of the Suspended Particulate Matter (SPM). The sampler draws the air with the help of high flow rate blower at a nominal flow rate of 1. 4 cubic meters per minute. The air passes through the cyclone inside the sampler, the coarse and non-respirable dust is separated from the air stream using the centrifugal force and is collected inside a sampling bottle. This dust size varies from 10 to 100 microns. The fine dust with a diameter of less than 10 microns will pass through the filter paper.
- Particle Collection : The sampler serves as particle collector that collects the particles less than 10 microns on filter paper and bigger than 10 microns in a sampling bottle with the helps of a cyclone separator.
- Bower Motor : The sampler features bower motor instead of high speed blower. This is a brushless and noiseless motor with no carbon brushes.
- Programmable Timer & Relay : The sampler possess programmable relay that helps in setting ON time and protects the motor in case of high or low voltage conditions.
