Extech BR95-CO Carbon Monoxide Gas Sensor Module, Electrochemical, 0-1000 ppm, Analog Output

The Extech BR95-CO stands out as a dedicated carbon monoxide detection module built around electrochemical sensing technology, delivering precise and reliable measurements for safety and air quality applications. Unlike generic gas sensors, this compact module offers a focused detection range of 0 to 1000 ppm with 1 ppm resolution, making it suitable for both industrial monitoring and HVAC systems.

Highlights

• Electrochemical sensor technology for accurate CO detection
• Detection range: 0 to 1000 ppm with 1 ppm resolution
• Fast response time: T90 under 30 seconds
• Analog voltage output for easy integration
• Wide operating temperature range: -20°C to 50°C
• Compact dimensions: 52 x 24.5 x 23.9 mm

In daily use

The BR95-CO is designed for continuous monitoring in environments where carbon monoxide may accumulate. Its electrochemical cell provides stable readings over a sensor lifetime exceeding two years. The module requires a warm-up time of less than five minutes before reaching full accuracy, and it operates within a humidity range of 15% to 90% RH (non-condensing). The analog voltage output allows connection to microcontrollers or data loggers via a standard pin header.
