APM 550 Mini

APM 550 Mini

  • Time totalizer: Records the actual time duration of each sample
  • Vacuum Pump: Oil Free, light weight pump driven by brushless induction motor
  • Size & Weight: Compact & Light: Single unit compact cabinet made of Aluminum is light and robust
Ambient Air enters the APM 550 MINI sampler through an omni-directional 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 in the APM 550 MINI are based on designs standardized by USEPA and as such the system complies with international norms for PM 2.5 Samplers. The sampling rate is held constant at 1 m3hr by a critical orifice. A special light weight oil free pump has been used in the instrument and adequate cooling air draft has been provided to ensure that the operating temperature near the filter holder remains close to ambient temperature. Sampling rate is continuously displayed on a built-in rotameter while the duration of sample is available through a Time Totalizer. Special features: PM10 and PM2.5 Impactors of sampler based on designs standardized by US EPABrushless, Oil-free, light weight pump practically requires no maintenanceFilter holder designed for any 47mm diameter filter mediaCritical Orifice maintains constant sampling rate of 1 m3hourProvision to attach gaseous samplerCompact cabinet design for easy portability

WM 271 Wind Monitor

WM 271 Wind Monitor
  • Feature Ethernet Or Modems Reduced Power Consumption. New Battery Backed Power-pack With Optional Solar Panel Charger Enables Operation In Open Fields New Windows Compatible Software Allows:
  • Specifications Wind Speed : Envirotech WS-10 range 0 to 100 Km/hr. Wind Direction: Envirotech WD10 range 0 to 360

Reliable information of wind movements is a critical requirement for air quality management. Polluting gases and particulates released from elevated industrial stacks disperse by a variety of mechanisms and by the time the pollutants reach ground level their concentration is reduced to a fraction of the emitted level. The extent of dispersion and the resultant ground level concentration (GLC) depends upon local meteorological parameters like wind speed, wind direction, atmospheric turbulence or stability and the mixing height. Reliable local wind data can also help to identify possible sources that could be adversely affecting air quality in an area. Envirotech Wind Monitoring Systems have been used for past several years all over the country by consultants, industry and researchers to generate micro-meteorological data. Feedback from this large body of users has often led to system upgrades. The WM271 is our latest model Wind Monitor with important new features specifically incorporated for Indian field use

APM 433 Gaseous Pollutants Sampler
The APM 433 Gaseous Pollutants Sampler has been designed for monitoring Gaseous Pollutants like SO2, NO2, Cl2, H2S, O3, NH3 etc. in ambient air. The APM 433 is an independent stand-alone monitoring instrument (unlike our gaseous sampling attachments APM 411 and APM 411 TE that need to be paired with a dust sampler). A suction pump is also made an integral part of the sampler, besides a flow-meter, time totalizer and timer. Sampled air is bubbled through suitable reagents that absorb specific gaseous pollutants and the absorbing media analyzed as per standard wet chemical methods.
