- Compliant with Standard RESET grad B
- Compliant with WELL Building Standard® (WELL v2™).
We at Senseair believe in quality and accuracy. When it comes to gas measurements, you want a sensor that you can always trust - without the need for maintenance. Equipped with a self-correcting algorithm (ABC: Automatic Baseline Correction), you can mount your Sunlight sensor and then leave it alone for 15 years while maintaining a robust system. Our Sunlight sensors are optimized for battery and wireless applications, or in places where you need a reliable and secure sensor with a long life.
Using LED as the light source, ultra low power consumption no longer has to come at the cost of accuracy.
