Product Description

Product Description

The ES4-NO2-1000-01 Nitrogen Dioxide Gas Sensor is a high-performance, amperometric sensor designed for precise detection of nitrogen dioxide (NO2) in a wide range of environments. Built using solid polymer electrochemical sensing technology, this sensor provides accurate and reliable measurements even at high concentrations, making it ideal for applications in air quality monitoring, environmental research, and industrial safety.

Key Features:

• High Sensitivity & Accuracy: The sensor delivers a sensitivity of 10 nA/ppm ± 3 nA/ppm, with a lower detectable limit (LDL) of just 2 ppm. This ensures reliable detection across a wide dynamic range from 0 to 1000 ppm, with a maximum overload capability of up to 5000 ppm.
• Fast Response Time: The sensor exhibits a rapid response time with T50 < 10 seconds and T90 < 30 seconds, enabling quick detection and real-time monitoring of nitrogen dioxide levels.
• Long-Term Stability: The sensor features a long-term drift of < 1% per month and minimal zero drift in clean air (< 0.2 ppm), ensuring stable performance over time.
• Robust Design: The ES4-NO2-1000-01 comes in a compact housing made from durable PPO material, weighing less than 6g. It is designed to operate effectively in harsh environmental conditions, with an operating temperature range of -40°C to +55°C and humidity tolerance of 15-95% RH (non-condensing).
• Low Cross-Sensitivity: The sensor shows minimal interference from common gases such as ammonia (NH3), carbon dioxide (CO2), methane (CH4), hydrogen (H2), and many others, ensuring accurate measurements even in complex air mixtures.
• Fast Warm-Up Time: The sensor warms up quickly in under 60 seconds, enabling rapid deployment and immediate monitoring.

Typical Applications:

• Air Quality Monitoring: Ideal for use in monitoring nitrogen dioxide concentrations in outdoor and indoor environments, including parking garages, industrial sites, and urban areas.
• TLV (Threshold Limit Value) Monitoring: Helps to ensure compliance with occupational safety standards by accurately measuring nitrogen dioxide levels in work environments.
• Environmental Research & Control: Essential for research institutions and environmental agencies monitoring air pollutants in real-time.
• Safety & Detection Systems: Provides reliable gas concentration readings for emergency response systems and industrial safety devices.

Performance Specifications:

• Operating Temperature Range: -40°C to +55°C
• Operating Humidity Range: 15-95% RH (non-condensing)
• Long-Term Drift: < 1% per month
• Sensitivity: 10 nA/ppm ± 3 nA/ppm
