Handy Sampler

March 10, 2023

Description

This handy air sampler is portable and operates on both a mains power source and a rechargeable battery. For the purpose of monitoring air quality, this is helpful for gathering air samples. This is the best monitoring tool for indoor air quality.

It includes a pump, a digital timer, a rotameter (0–5 LPM), and a flow controller with space for storage sampling equipment in a small stainless steel box. uses a rechargeable lead acid battery from SMP. When ingested, chemical compounds that are disseminated in the office environment as gases, vapours, and aerosols may have a variety of harmful health impacts. To assess the quantities of contaminants, the Handy Sampler is employed.

Uses

include the identification of air contaminants such dust, acid mist, ammonia, H2S, and free chlorine.

the evaluation of individual exposures.

the general background levels to be discovered.

to assess the success of the control.

to determine STEL and TWA values.

Analytical Sampling Devices: The type of contaminant will determine which analytical procedures are used.

FILTER PAPER HOLDER FOR DUST MONITORING - The gravimetric method may be used to measure dust. if it contains metals or compounds made of them. The Atomic AbsorbtionSpectophotometer can be used to analyse it.

IMPINGERS FOR GAS & VAPOURS ANALYSIS OF ORGANIC GAS SUCH SO2, NOX, ETC. It uses the titrmetric or spectrophotometric method.

ACTIVATED CHARCOAL TUBES FOR HYDROCARBON AND SOLVENT VAPOURS ANALYSIS - Organic pollutants are gathered on absorbent material (Activated Charcoal, Silica Gel), then desorbed and examined byGC with an appropriate detector.

Physical Design Highlights: KDM Global is made up of an electronic assembly, a flow controller, a suction pump, a flow measuring device, and a sampling train. Two glass impingers that are encased in thermocole housing may be found in the sample train. A single flow measuring device and a single flow control device are utilised, and the two impingers are pneumatically coupled in series to allow the sampled air to pass through them one after the other in succession. As a result, it only allows for the sampling of one pollutant at a time. Glass impingers are filled with pollutant-specific adsorbent solutions in order to trap the desired contaminants. Each sampler has all the components and subassemblies and is composed of corrosion-free stainless steel.

A diaphragm-style suction pump is used for sampling.

One low range precision rotameter is used to measure airflow. A tiny ball valve connected in series with the sample pump controls the flow of fluid.

Important Details:

• Helpful for employing two impinger tubes to sample one gas at a time.

Used for shop floor or ambient air quality monitoring, using an internal battery charger and an external converter as a DC supply.

• Electronic Timer With Microprocessor and Cumulative Totalizer

• Small size and light weight
