Alphasense will be showcasing a number of new sensor products alongside its legacy portfolio at Sensor + Test 2023.

At just over seven centimetres wide and two centimetres high, the new OPC-R1 sensor from Alphasense is extremely small in comparison with previous technologies. However, with outputs for PM1, PM2.5, PM10 and histograms for up to 16 ‘bins’ the sensor provides considerable particulate monitoring capability.

A new version of the optical particle counter from Alphasense has been launched. The new OPC-N3 retains all of the advantages of its predecessor (OPC-N2) with the added benefit of automatic range switching covering PM10, PM2.5 and PM1. With an expanded measuring range (0.38-40µm), the OPC-N3 is able to measure the particulate fractions of most interest; from the finest of particles up to larger particles such as pollen.
