The APM560 DFC Respirable Dust Sampler is designed for accurate monitoring of respirable particulate matter in industrial and environmental conditions.

• Sturdy powder-coated aluminium cabinet houses blower, filter holder, and Digital Flow Controller (DFC)

• Digital Flow Controller (DFC) automatically maintains constant flow and compensates for dust load

• Auto shut-off protection when airflow drops below set limit

• Flow rate: 0.8 – 1.4 m³/min (electronically stabilized)

• Programmable timer: 0–24 hours (user selectable)

• Digital time totalizer: 0 – 9999.99 hours with LCD display

• Flow measurement: Glass manometer tube calibrated directly in m³/min

• Cyclone separator (10 µm D50 cut-off) for respirable dust sampling

• Coarse dust (>10 µm) collected in dust cup

• Fine particles (10 µm to 0.1 µm) collected on filter paper

• Casted aluminium filter holder with rubber gasket for leak-proof sealing

• Heavy-duty brushless blower, noiseless operation

• VFD controlled, 220V AC ±20V, 50 Hz single phase supply

• Continuous operation up to 28 hours

Applications:
Ambient air quality monitoring, industrial hygiene studies, occupational exposure assessment, environmental monitoring, pollution control boards, research institutions.

High-precision digital flow meter designed for accurate air and gas measurement. Supports a wide flow range from 0.1 to 20 LPM with fine 0.01 LPM resolution and ±2% accuracy. Measures flow, volume, time, temperature, and barometric pressure on a clear 126 × 64 GLCD display. Comes with a rechargeable battery and 220VAC charger, making it ideal for both field and lab applications.
