PM 10/RESPIRABLE DUST SAMPLERS
 Model: APM 460 BL

The APM 451 Respirable Dust Sampler based on CSIR NEERI knowhow. The system was upgraded to APM 460 in 1997. The APM 460 sampler uses an improved cyclone with sharper cutoff (D50 at 10 microns) to separate the coarser particulates from the air stream before filtering it on the glass microfibre filter.


 Model: APM 460 NL

The APM 451 Respirable Dust Sampler based on CSIR/NEERI knowhow. Withmore than 1000 instruments of this model currently operating in the field, the APM 451 forms the backbone of the National Ambient Air Quality Monitoring Network and is in widespread use by Consultants and a wide spectrum of industries.


Model: APM 460 NLDX

The APM 460DXNL incorporates the suggestions and provides a top of the line model for the discerning buyer who is not constrained by cost considerations and for those who will settle only for the best.


Model: APM 541:

Ambient Air enters the APM 541 sampler through an omni-directional inlet designed to provide a clear aerodynamic cut-point for particles larger than 10 microns. The PM10 impactor used in the APM 541 is based on designs standardized by USEPA and as such the system complies with international norms for PM10 Samplers.



GASEOUS SAMPLING ATTACHMENT
 Model: APM 411:

The Respirable Dust Sampler is essentially a particulate sampling system requiring a high flow-rate. Gaseous sampling requires only a few LPM of air flow. Respirable Dust Samplers are provided with a suction port and mounting hardware to facilitate interface of the Gaseous Sampling Attachment APM 411.


Model: APM 411 TE:

The APM 411 TE Gaseous Sampling Attachment is designed to operate with Respirable Dust or High Volume Samplers and incorporates several improvements based on suggestions and feedback from thousands of users of APM 411 gaseous sampling system.



PM 2.5/samplers: APM 550:

Recent studies sponsored by USEPA have concluded that Fine Particles, (PM2.5)which penetrate deep into the lungs, are more likely to contribute to health effects.Fine Particulate Matter (FPM) also adversely affects visibility.


Organic Vapour Sampler: APM 856:

Recent addition of Benzene in petrol, in place of a lead compound, has made Benzene and its derivatives a part of vehicular pollution. Already Benzene concentrations in high traffic areas and near petrol pumps have become a matter of concern. Unfortunately a majority of these compounds are highly toxic and many have been reported to be carcinogenic. Organic compounds are also reported to be pre-cursers for Ozone formation and play a role in secondary formation of oxidants.


Soap Film Calibrator

Model: Apm 520: The Envirotech APM 520 Flow Calibrator is designed to provide a reliable and portable flow standard for flow verification of environmental sampling systems. The APM 520 is a primary standard flow calibrator based on a glass body soap bubble meter.

SOUND LEVEL METER:
SLM 100 integrating sound level meter:

The SLM 100 Sound Level Meter has been designed for ease in field operation. All features considered essential for field surveys have been included. The SLM100 is a “Type 2” Integrating Sound Level Meter designed to meet the requirements of IS 15575 (Part1) 2005. The instrument has a frequency weighting of “A” type and allows the user to select Slow or Fast mode of measurement.


METEOROLOGICAL INSTRUMENT AND SENSORS

Datalogger:  WM 271: 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.



Barometric Pressure Sensor: 090D,091:   Convert absolute atmospheric pressure into a linear, proportional voltage, which may be used in any meteorological program. These sensors are inherently stable devices that do not require periodic service or routine recalibration.



APM 800 Personal Sampler

Model: APM 800:  This instrument has been developed in accordance with the requirements of the Factories Act 1948 (amended in 1987/88) which provides for a regular monitoring of work-space environment and of exposure of workmen to harmful pollutants and toxic materials.



APM 821 Handy Sampler

Model: APM 821::  The increasing general awareness of atmospheric pollution and its hazards to the health and well-being of industrial workers is bound to result in greater stress on accurate, reliable and frequent assessment of work place pollution and workerexposure.
