PCE Instruments PCE-PQC 23US Particle Counter

Overview

The PCE Instruments PCE-PQC 23US is a portable particle counter designed for indoor air quality monitoring in cleanrooms, pharmaceutical manufacturing, and HVAC systems. It measures particle concentrations across six size ranges (0.3, 0.5, 1.0, 3.0, 5.0, and 10.0 μm) with a fixed flow rate of 2.83 L/min compliant with ISO 21501-4 and JIS B9921 standards. The device includes integrated sensors for CO2, temperature, and relative humidity monitoring.
