Excessive dust exposure at the workplace does not only endanger the health of employees and colleagues. Inventory, products that are to be processed and technical equipment also suffer from increased particle concentrations in the room air. For this reason, many countries have established statutory limit values for fine dust concentrations. Complying with these limit values must be regularly checked, especially in the workplace, but also in schools, daycare centres, care facilities and public authorities.

Inspecting the air quality made easy BQ21 with bluetooth^® connectivity

With the smart bluetooth^® hand-held measuring device BQ21, you can keep an eye on the particle load in the surrounding air even over longer periods of time. The particle measuring device with a flash memory for 5,000 data sets records all health-relevant room climate parameters such as air temperature, humidity level and dust fractions (< 10 micrometres) as PM10 and PM2.5 according to the internationally acknowledged PM standard (Particulate Matter, number, size and mass concentration of particles in the air). The air pollution is displayed on the 2.0 inch colour display either numerically in micrograms per cubic metre (µg/m³) of room air or as number of particles. Moreover, a colour bar indicates the current particle burden.

Acoustic alarm signal for poor air quality

Particularly convenient: The limit values for good air quality defined by the WHO (World Health Organization) are already saved in the BQ21. If the particle load or particle concentration exceeds the WHO alarm limit, an acoustic signal will be emitted.

Evaluation and documentation including MultiMeasure mobile app

As an environmental measuring device of the latest generation, the BQ21 is 100 per cent "MultiMeasure Mobile ready" and thus prepared for all requirements of professional measurement data evaluation and documentation. Via the integrated Bluetooth^® interface, the recorded measurement data is easily and conveniently transferred to a smartphone or tablet, where it can be professionally evaluated or recorded with the free MultiMeasure Mobile app.

The advantageous combination of the BQ21 and professional MultiMeasure mobile evaluation software allows you at any time to quickly and reliably draw statements about the prevailing fine dust concentration in the room air. With our professional, cloud-based software MultiMeasure Professional, a wide range of analysis options is included such as the logging function for long-term measurements, graphic evaluations, the report function and data synchronisation.

With the free MultiMeasure Mobile app the captured measurement data becomes even more transparent. Just like the analysis software MultiMeasure Studio Professional 2.0 developed by Trotec for administration, analysis and report generation of measurement data on your PC, the free MultiMeasure Mobile app for Android and iOS devices also allows for professional measurement data management with a multitude of useful functions. The BQ21 hand-held measuring device and numerous other measuring devices with bluetooth^® interface are automatically identified by the app and can be quickly, easily and wirelessly connected to the mobile terminal device.

The functionality of the MultiMeasure Mobile app is way beyond the simple indication of the captured measurement values. All recorded data can be displayed either numerically or in form of a chart and, by means of the logging function, can also be recorded as a series of measurements for long-term evaluation. Assigning measurement data to different projects (e.g. departments, rooms, buildings, etc.) with the app that handles a great number of clients is a child's play – including text and report templates for professional measurement data reports.
