Check your indoor air quality (IAQ) by measuring the amount of particles present. These counters are often used to monitor dust levels in workshops, check for particles in classrooms, and measure filter efficiency in HVAC systems. The sensor probe detects and identifies particles of six different sizes, helping you confirm that your clean room complies with ISO Class requirements. First, use the zero count filter to establish a baseline before taking a sample. Then, either measure the amount of air particles detected within a set time range or the amount of air particles detected within a certain air volume. Counters store up to 10,000 readings in their internal memory, and you can transfer data to your computer via Ethernet or USB connection—no special software required. Compact, lightweight, and battery powered, these counters are portable and able to operate in tight spaces. They’re CE marked as compliant with European health, safety, and environmental standards.
