Cubic handheld particle counter OPC-6511DS adopts the principle of light scattering with a built-in unique laser diode, consistent RPM fan, and well-designed ultrasonic flow sensor. The handheld air particle counter is compliant with lSO 21501-4 requirements. Equipped with a high-capacity lithium battery and a user-friendly touch screen, the device displays monitoring data in real time, enabling efficient spot-checking across multiple sites.
5-channel outputs 0.3μm, 0.5μm,1.0μm, 5.0μm,10μm in pcs/28.3LPM or pcs/m³.
Sound and light alarm once particle quantity exceeds the set threshold.
Calibration coefficient correction available against standard equipment.
Real-time display ISO14844-1 grade level.
Built-in rechargeable Li-battery.
