NO-A1 Nitric Oxide Sensor

NO Gas Sensor, Electrochemical, A-Series, 0–250 ppm NO

Reliable nitric oxide monitoring for industrial safety and emissions applications.

The NO-A1 sensor is a ppm-level nitric oxide sensor designed for a broad variety of instrumentation, including portable gas detectors and fixed systems used in industrial safety, environmental air quality analysis and process control. The standard 0–250 ppm NO-A1 sensor is ideal for general and industrial safety and emissions monitoring.

Available in the widely adopted A-Series footprint and as NO-A1+ with Integrated Smart Technology, it supports plug-and-play operation with on-board temperature sensing and stored calibration data to simplify instrument design
