Trotec BQ21 Mini Air Quality Particle Meter
£303.48
The Trotec BQ21 Mini Particle Meter is a compact, professional air quality monitor designed to measure airborne particle concentrations and indoor climate conditions. Ideal for workplaces, schools, healthcare settings and public buildings, it helps ensure a healthier environment by monitoring fine dust levels and supporting compliance with workplace air quality standards.
The easy-to-read 2-inch colour display simultaneously shows all key measurements, while the built-in colour warning indicator and audible alarm provide instant notification when particle concentrations become elevated. With storage for up to 5,000 measurements, the BQ21 is ideal for routine monitoring, inspections and reporting.
The BQ21 also connects via Bluetooth® to the MultiMeasure Mobile app, allowing users to record, analyse and report measurements directly from their smartphone or tablet.
