The Most Effective Way to Measure High CO₂ Concentrations

The STC31 is a chip-sized gas concentration sensor for high range, accurate CO₂ measurements designed for high-volume production. The sensor is based on a revolutionized thermal conductivity measurement principle, which results in superior repeatability and long-term stability. This makes the STC31 the perfect choice for applications where reliability is key. Thermal conductivity technology has an ultra-low power consumption, even compared to low-power optical sensor. This makes it the ideal choice for battery operated applications, delivering top-performance at an absolute minimal power budget.
