e-Series Nitrogen Oxides Analyzer NO, NOx & NO₂

AC32e

Precise PM1, PM2.5, PM4.25, PM10 and TSP monitoring in indoor ambient air.

Eco-designed, reference air quality monitor, based on the chemiluminescence technology, the standard method for the measurement of nitrogen oxides (EN 14211). QAL1 certified by the TÜV, US-EPA approved. With its ultra low power consumption & 24 V supply (option), the AC32e is the sole NOx analyzer on the market able to measure without being connected to the power grid.

Multi-screen remote access via Wifi or Ethernet using the ENVEA Connect™ application for control, diagnostics, software upgrade
