While buying a air handy sampler which specification we should know
Briefly

Choosing the right portable air sampler for fieldwork involves several crucial specifications to consider, including the flow rate, pump type, battery life, and overall portability. Ideal flow rates range from 0.2 to 3.0 LPM, offering flexibility for various particulate types. Diaphragm pumps are preferred for their durability, particularly in long-term use. Strong battery life—which should ideally last at least 8 hours on a single charge—is critical for outdoor excursions. A compact size helps ease transportation, while optional features like cyclones can enhance sampling specificity. Serrax Technologies has a model that meets these criteria well, aiding users in environmental monitoring.
Flow rate is crucial in determining how much air is sampled, ideally between 0.2-3.0 LPM, allowing flexibility for different particulate sampling needs.
The pump type is important; diaphragm pumps are the most reliable for durability and stability in long-term outdoor field usage.
Battery life is essential for field operation, with at least 8 hours of runtime on a full charge being ideal, especially for outdoor use.
Portability matters—look for compact dimensions like 155 x 60 x 85 mm to ensure easy transport during field studies.
