Carbon Dioxide Sensors
Although sold individually online, for a moderate order we can customize these sensors to meet your unique OEM requirements and budget.
Our infrared carbon dioxide co2 sensors are accurate, respond very quickly to changes in carbon dioxide levels, are self-calibrating, and do not have a limited shelf-life, making them a great long-term value. In addition, all our sensors include documented, industry-standard I/O ready to use in any project.
Electrochemical Gas SensorsWe offer a full line of electrochemical-based sensors. These sensors are known for their stability, the wide range of gases detectable, and their exceptional sensitivity. We offer a complete line of electrochemical sensors for many gases.
