NO-A41 Nitric Oxide Sensor

NO Gas Sensor, Electrochemical, A41-Series, 0–20 ppm NO (ppb-level noise)

Low-noise 4-electrode nitric oxide sensor for sensitive NO monitoring

The NO-A41 sensor is a 4-electrode nitric oxide sensor in the standard A-Series footprint, offering low noise and high resolution for sensitive NO measurements. These NO-A41 sensors are ideal for applications requiring low noise and high resolution.

Combined with an appropriate low-noise analogue front end, NO-A41 sensors support ppb-level NO monitoring in compact instruments that still require the mechanical convenience of the A-Series package..
