Gas sensor at ppm level
A small, versatile, and high precision 3-channel NDIR sensor for CH₄ and CO₂ sensing
A breakthrough in the NDIR sensing! With the K96 proof of concept, Senseair introduces a very novel approach to measure simultaneously 3 different species with one mid-IR source. Senseair K96 is a module that is designed for simple integration into products. Every sensor is individually calibrated and is provided with UART digital interface. It offers new cost-effective alternatives for a wide variety of applications related to GHG (CO₂, N₂O, CH₄) monitoring.
Key benefits:
- 3 species measured simultaneously.
- High precision
- Maintenance free
- Long lifetime
- Individually calibrated with temperature compensation
- Possibility to correct cross-sensitivities between gas species using the dedicated NDIR channels.
