Description

OX-B431 O3 Sensor + NO2 Sensor Description
Alphasense is expanding its line of electrochemical toxic gas sensors to address industry-specific requirements, including emissions monitoring, process safety, environmental monitoring and VOCs.

Ozone (O3)

The new O3-B4 measures Ozone at low ppb concentrations. Low sensitivity to SO2 and repeatable sensitivity to NO2.

OX-B431 O3 Sensor + NO2 Sensor Features

  1. High resolution up to 15ppb
  2. Short response time of 45s
  3. Linear output, excellent linearity
  4. Little zero drift
