S8 2%

Small components and advanced design for control- and alarm applications. The sensor can be integrated into a wide range of different alarm applications where you want to detect CO2, such as leakage detection.

  • Miniature size
  • Easy integration
  • Individually calibrated
  • Maintenance-free
  • Long term stability

More than 25 years experience of research and development within the field of infrared gas sensing has now brought us the smallest CO2 sensor, with NDIR- technique, in the world – Senseair S8 2%. The new sensor has excellent performance such as high accuracy and low power consumption.

Senseair S8 2% is designed for high volume production with full traceability by sensor serial number on all manufacturing processes and key components. Every sensor is individually calibrated and is provided with UART digital interface.

The sensor is maintenance-free and has an estimated life time of more than 15 years. Senseair S8 2% is a module that is designed for simple integration into products. Senseair S8 2% can be used in a wide range of applications such as in ventilation control to improve energy savings and to assure a good indoor climate. Other fields of use are personal safety and measurements to increase process yield and to increase economic value in bio-related processes.
