About the Optical Dust Sensor OPC-N3

The Optical Dust Sensor OPC-N3 from Alphasense is a proven solution for ambient monitoring applications across the manufacturing sector. Compact optical particle counter for ambient dust monitoring. USB and SPI output for IoT integration.

Engineered to 24 size bins bins, 0.35–40 µm range, 5.5 L/min flow, this unit is built for demanding industrial duty cycles.

Tunnel Fox sources the Alphasense Optical Dust Sensor OPC-N3 directly from authorised distribution channels, so every unit ships with original-equipment-manufacturer (OEM) traceability — critical for plants running ISO-certified maintenance programmes or warranty-backed asset registers.

Alphasense has a long-standing reputation for delivering reliable ambient monitoring components, and the Optical Dust Sensor OPC-N3 fits naturally into greenfield builds, brownfield retrofits, and routine replacement cycles. Whether you need a single replacement unit for an emergency shutdown or a bulk order for a scheduled maintenance window, our procurement team will confirm availability, lead time, and landed cost in writing — usually within one business day.

For South African industrial operators, getting the right ambient monitoring component on site quickly often makes the difference between a contained downtime event and a full production outage. We hold quote-ready relationships with global Alphasense distribution partners and can ship to mine sites, processing plants, ports, and workshop addresses anywhere in the country.
