QB1 Constant flow sampler

QB1
The QB1 series are portable, robust samplers designed to ensure consistent and precise performance, both in emission measurements and in air quality sampling.
Three configurations for every sampling need


Sensor calibration is quick and intuitive: corrections are entered directly into the instrument, ensuring integration into the metrology chain without post-sampling interventions. Management is via OLED display and tactile keyboard or via Dadolab Companion APP, which allows quick settings, real-time notifications, download and remote data sending.

QB1: compact, configurable and compliant with international standards, with in-line filter, automatic pressure drop compensation, vacuum gauge and temperature sensor in the DGM for reliable and safe sampling.
