e-Series Ozone analyzer O₃

O342e

LED based, UV Photometric Ozone Analyzer providing accurate, stable and repeatable O₃ measurements in the range of 0-500 ppb or 0-10 ppm

Ozone monitor for regulatory compliance: QAL1 certified by the TUV, US-EPA approved. Eco-designed, reference air quality monitor using LED based UV Photometry technology (patented). With its ultra low power consumption & 24 V supply (option), the O342e is the only ozone monitor 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
