NO-D4 Nitric Oxide Sensor

NO Gas Sensor, Electrochemical, D-Series, 0–100 ppm NO

Compact nitric oxide sensor for clip-on and wearable personal safety devices

The NO-D4 sensor is a miniature nitric oxide sensor developed for space-constrained instruments such as clip devices, handheld monitors and wearable personal safety detectors. These miniature NO-D4 sensors are ideal for personal and industrial safety instruments where space is limited

With its low-profile D-Series package, NO-D4 sensors deliver fast response times and strong signal levels, making it suitable for safety-critical NO monitoring in industrial environments.
