Dust Samplers

When it comes to innovation in Ambient Air Sampling technology, Instrumex has delivered yet again! The most common hassle faced by Consultants in order to comply with the CPCB norms for Ambient Air Sampling - was using two separate instruments for measurement of PM2.5 & PM10 Dust. Instrumex has found the solution to this problem - The Dual Channel Sampler for measurement of PM2.5 & PM10 dust concentrations in ambient air – Simultaneously!

The flow control module uses the proven technology used in Instrumex's IPM-FDS 2.5/10µ Fine dust Sampler that has enjoyed over 400 installations across India and abroad. The two channels in IPM-FDS-2510 are individually controlled by separate flow control element but integrated into a single controller module. Thereby giving precise microprocessor based flow control for two channels. Both the channels individually comply with Federal Reference Method of USEPA as described in 40 CFR Part-50 Appendix L for determination of Particulate Matter. It also confirms with the CPCB guidelines for Measurement of Ambient Air Pollutants.

Features

• Dual channel enables measurement of PM-10 & PM10 Simultaneously
• PM-10 Confirms to 40 CFR, Part 50 Appendix J of USEPA
• PM-2.5 Confirms to 40 CFR, Part 50 Appendix L of USEPA
• Microprocessor based Precision flow control for each channel
• Data Logging of all parameters for each channel
• Data Retrieval by USB and RS-232 ports
• Extremely portable with Foldable tripod stands and carry case

Instrumex Respirable Dust Sampler is a versatile dust sampler that is based on a design standardized by CPCB for collection of PM10 & Totoal Suspended Particulates (TSPM) in ambient air and also simultaneously samples the particulates having aerodynamic diameter less than 10 Micron.

Features

• Simultaneous Sampling of PM10 & TSPM
• Brushless & Noiseless Blower Motor
• Programmable Timer
• Rugged construction for heavy duty usage
• Voltage Protection Relay for superior motor protection

Instrument Overview

Instrumex Respirable Dust Sampler employs heavy duty Brushless and Noiseless blower that draws air through a size-selective inlet and through a 20.3 X 25.4 cm (8 X 10)" filter at a flow rate, which is typically between 0.9 — 1.4 m3/min maintained by an Orifice. A cyclonic flow technique is used to separate the particles with aerodynamic diameter less than the cut-point of the inlet (PM10). These are collected by the filter. The particles greater than 10 micron are separated at the bottom of the cyclone into a dust collecting bottle. The mass of PM10 particles is determined by the difference in filter weights prior to and after sampling. The concentration of PM10 in the designated size range is calculated by dividing the weight gain of the filter by the volume of air sampled.

Gaseous Sampling

Normal Gaseous Sampling Kit:

Aluminum enclosure housing an Ice tray attached at the back of the instrument with following provisions:

• Impinger stand for 4 nos. of glass impingers.
• 4 Way acrylic manifold with needle valves for precision flow control
• 0.3 - 3LP M rotameter for flow setting
• 4 Nos. of glass Impingers. (cap. 35m1.)

Thermoelectric Gaseous Sampling Kit:

In tropical weather where temperatures can soar above 35°C, the reagents in the impingers tend to evaporate quickly. This results in erroneous reporting of the Gaseous pollutants. Instrumex Thermoelectric Gaseous Sampling Kit is a separate enclosure with a Peltier cooling system that automatically maintains temperature between 10 - 15°C. Thereby completely eliminating the hassle of replacing the ice/cold water after every few hours

Optional Extras

• Chemical Kit for sampling of SO2, NO2, NH3 & 03
• Dust Sampling Bottles G FA Filter papers, Size (8x10)"
• Whatman EPM 2000 filter paper, Size (8x10)"

Instrumex Ambient Fine Dust Sampler is designed as per USEPA guidelines for sampling of PM2.5 and PM1 0 particles in Ambient Air. The USEPA based WINS impactor separates the particles smaller than 2.5p by the principle of impaction at a regulated flow of 1 m3/hr. A critical orifice controls the flow throughout the sampling period. PM1 0 particle sampling is achieved by replacing the WINS impactor with a downtube.

Key Features

• Light Weight & Low cost monitoring Solution
• Confirms to U.S. EPA guidelines
• Choice of Sampling inlets for PM2.5, PM10 and TSP
• Construction suitable for outdoor use

Clock / Timer System

Programmable Real Time control system with automatic start & stop Digital display of date, time & time of sampling. Accuracy ± 2 min / month.
