DROP Enviro Engineers & Service made Respirable dust sampler ,PMI-410 NL sampler uses an improved cyclone (with sharper cutoff) to separate the coarser particles (>10 microns) from the air stream before filtering it on the 0.5 micron pore size filter allowing measurement of both TSP and Respirable fraction of suspended Particulate Matter (SPM). our customers demand that high noise level is one main bottleneck for monitoring ambient air quality around schools, hospitals, libraries, institutional areas, wildlife sanctuaries and other noise sensitive areas. To moot this application specific requirement, we have, introduced PMI-410 NL which incorporates a noiseless brushless & Belt-less continuous duty Turbine blower.

The PMI 425 instrument is manual machine used for sampling of Fine particles (PM2.5) from Ambient air & based on impactor design as per USEPA, Ambient air enters through an omni-directional inlet designed to provide a clean aerodynamic cut-point for particles ‘greater than 10 microns. Particles in the air stream finer than 10 microns proceed to a second impactor that has an aerodynamic cut-point at 2.5 microns. The air sample ond fine particulates exiting from the PM 2.5 impactor are passed through a 47 mm diameter Teflon fiter membrane that retains the fine particulate matter. ‘The PMI 425 having customized specially made Rotameter which having 16.67 LPM indicated flow mark & with Dry Gas Meter to provide a direct measure of the total air volume sampled.light weight, sturdy Aluminium cabinet, more compact, can be carried in a Car trunk and is ideal for field use.

Low Flow Air Sampler is an easy-to-carry around sampler for determining the concentration of toxins in ambient and workplace environments. HS 1 is a compact, light weight battery operated sampler which is is designed for determination of toxic pollutants such as SO2, NO2, Cl2, NH3, H2S etc. in ambient and workplace environments. The sampler employs wet chemical methodology for sampling the air for toxic gas and other pollutants. HS 1 system uses a small battery operated pump to draw air thorough a suitable absorption solution contained in an impinger. If necessary, 3 impingers can be used in series to monitor 3 gaseous pollutants. There is an additional provision to determine suspended particulates in the same exercise by using the open sampling head which takes 35mm diameter filters.

Rechargeable batteries have been used with sufficient storage to operate the system for 5 hours making it easier to compare

Stack Sampler is a basic instrument used for Particulate matters (PM) under Isokinetic conditions and gaseous pollutants in flue gas emitted from the stack/chimney. Offered range is designed and manufactured as per the set industry norms using quality approved components with the help of advanced technology.
