The ES1-NO2-100 Nitrogen Dioxide Gas Sensor is a highly reliable, solid polymer electrochemical sensor designed for accurate detection of nitrogen dioxide (NO2) in various environments. Operating on an amperometric 3-electrode principle, the sensor provides precise measurements with a bias voltage of 0 mV and a recommended load resistor of 100 Ω. It offers a wide detection range from 0 to 100 ppm, with a fast response time of less than 10 seconds to 50% of full scale and less than 30 seconds to 90%. This sensor has a sensitivity of -20 nA/ppm ± 10 nA/ppm and a zero current of ±2nA, ensuring highly accurate results even at low concentrations. The ES1-NO2-100 is designed for long-term durability with an expected lifetime of over 3 years in air and a long-term drift of less than 1% per month. It operates within a wide temperature range from -40°C to +55°C and humidity levels between 15% and 95% RH, making it suitable for diverse environmental conditions. The sensor is lightweight (<0.7g) and compact, with a robust PPO housing material, making it easy to integrate into various applications such as TLV monitoring, parking garages, and air quality management systems. It also exhibits minimal cross-sensitivity to gases like ammonia, carbon dioxide, carbon monoxide, methane, and hydrogen, ensuring reliable NO2 measurements in environments where these gases may be present. With a 12-month warranty and a storage life of 12 months, the sensor is designed for easy use and disposal following local electronic waste regulations at the end of its service life.
