¹ Only available since firmware version 1046 or later.
² Estimated from the other particle fractions and bibliography, validated in the field (available via Modbus only).
³ See the NextPM User Guide for more information about these data.
⁴ Lifespan can vary depending on the operating conditions.
⁵ At concentrations above 1000 µg/m³, accuracy decreases due to a higher linearity error.
⁶ Calculated on the fifteen-minute moving average output.
⁷ This communication protocol requires a converter, as described in the “NextPM RS485” document.
