Mini particle measuring device BQ21
£252.90
Monitor indoor air quality with confidence using the Trotec BQ21 Mini Particle Meter. Designed for professionals, this compact handheld device accurately measures airborne fine particles (PM2.5 and PM10), while also recording temperature and relative humidity to provide a complete picture of your indoor environment.
Ideal for workplaces, schools, healthcare facilities, museums, warehouses and commercial buildings, the BQ21 helps identify poor air quality caused by dust and airborne particulates. An easy-to-read 2-inch colour display shows all measurements simultaneously, with a colour-coded air quality indicator and audible alarm providing instant warning when particle levels exceed recommended limits.
With built-in Bluetooth® connectivity, measurements can be transferred directly to the free MultiMeasure Mobile app, allowing you to analyse trends, generate reports and store data for future reference. The internal memory stores up to 5,000 readings, making the BQ21 ideal for routine inspections, environmental monitoring and long-term air quality assessments.
