Proven reliability, low cost, maintenance free

Models

K30 CO2 Sensor (030-8-0006) - for integration into high-volume OEM products.
K30 CO2 Sensor with Custom Outputs (030-8-0006-C) - Customize analog or digital outputs for your application. After ordering, email or fax the Custom Outputs PDF form and we will pre-configure your sensor’s settings. If the form is not received, your sensor will be delivered with default settings.
K30 CO2 Sensor Development Kit (CM-0024) - Easy to use, simply plug the sensor module into your PC via USB. Use our free GasLab® software to measure and graph carbon dioxide in real time or for data logging.
Sensor Development Kit (CM-200) - Easy to use, simply plug the sensor into the PCB and plug it into your PC via USB. Use our free GasLab® software to measure and graph carbon dioxide or use our library of source code on Github to build your own application or for OEM batch testing/configuration. Order sensors on this page, then order the Devkit here.

We recommend that all first-time users purchase either the CM-0024 or CM-200 Development Kit for fastest and easiest results.
