Our unique and patented HoloChip technology give laboratory-style identification and measurement of predefined gases:
• Multiple gases at cost of one
• Small size, low weight, low power
• Full flexibility in spectral and optical design
• A range of reproduction technologies
• Low cost in volume production
• Proven accuracy and long-term stability
In September 2009 OptoSense launched the first sensors for Demand Controlled Ventilation (CO2 and temperature).
Demand Controlled Ventilation with CO2 measurement boosts energy efficiency in both new and refurbished buildings. The major savings are achieved in buildings with high standards for indoor climate and with large variations or low predictability in occupation.

The HoloChips closes the gap between optical spectroscopy on the one hand and discrete filter-based systems on the other.
The sensors from OptoSense yield a higher accuracy and better long term stability, resulting in excellent Indoor Air Quality with the lowest energy and operational costs.
