  • Calibrating in-field PM air samplers with the FP-25

    Calibrating in-field PM air samplers with the FP-25 Flow measurement is critical to air monitoring processes, and quality data requires consistent airflow with minimal fluctuations. This is easy to achieve inside a lab where temperature, air pressure, and humidity are all carefully controlled. Of course, most environmental air monitoring takes place outside, where the instruments […]

  • STP/NTP tutorial

    STP/NTP tutorial Standardized flow references define the temperature and pressure conditions used to calculate flow readings. This allows flows measured under different conditions to be expressed according to a common standard, keeping readings accurate and comparable. Changing the standardized conditions (STP/NTP) is easy to do yourself. The tutorial below explains how to configure STP/NTP settings […]
