Handy Air Sampler HAS 2
Enables workplace monitoring to enhance workmen safety.
New Handy Air Sampler is more compact, lightweight portable battery operated instrument with digital display of Flow and sampled Volume which facilitates sampling of gases pollutant accurately.
Available Model : PEM – HAS 2
PEM–HAS 2 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.

Physical Design Highlights :
PEM–HAS 2 comprises a sampling train, a suction pump, a digital flow measuring device, an electronic flow controller and an Electronic timer-time totaliser, assembly. The sampling train accommodates two glass impingers which are housed in thermocole housing. The two impingers are connected pneumatically in series; the sampled air is made to flow through them in succession and therefore, permits sampling for only one pollutant at a time
Pollutant-specific chemical solutions are placed in the glass impingers for entrapping the pollutant of interest.
Sampler housing made of light weight ABS accommodates all the components and sub-assemblies.
The sampling suction pump is of diaphragm type.
Air flow is measured by a specially designed LFE and a precision low pressure sensor. The set flow is electronically controlled by PWM technique.
A microprocessor-based electronic unit carries out the various functions viz. timing, Time totalization (Cumulative Sampling Time), flow measurement, flow controller, volume totalization, sampling mode selection ( continuous or cyclic ) and Operator Machine Interface.
The LCD module (32 character alpha-numeric) display and the key pad serve as the Operator machine interface devices.
