Description
MAIYA • MST N4L N2O NDIR, Nitrous oxide sensor, 5%vol
MAIYA MST N4L N2O is a professional nitrous oxide sensor based on non-dispersive infrared (NDIR) technology. It is designed for stable N2O detection with strong selectivity, low cross-interference, and oxygen independence. The sensor supports a wide measurement range and provides fast response for use in gas monitoring equipment, analytical systems, and industrial safety applications. With TTL digital output and 0.4 to 2 V analog output, this compact sensor is easy to integrate into new designs or replacement projects. It offers a short preheating time, low power consumption, and a long service life, helping reduce maintenance needs. Suitable for professional use, it performs reliably across a broad temperature and humidity range.
