The K30 10% (100,000 ppm) CO2 sensor (formerly known as SE-0118) is a high performance CO2 sensor used commonly in scientific, medical, and biological applications. It is an accurate, low-cost solution for OEMs products like CO2 safety alarms or leak detectors.

Features

Built on tested K30 Sensor platform
Simple to install, pre-calibrated and ready-to-use
Proven reliability, low cost
Flexible analog and digital outputs

Models

030-7-0007 - K30 10% CO2 Sensor - For integration into high-volume OEM products.
030-7-0007-C - K30 10% CO2 Sensor with Custom Outputs - Customize analog or digital outputs for your application. After ordering, email or fax the Custom Outputs PDF form under the Documents tab and we will custom-configure your sensor’s settings. If the form is not received, your sensor will be delivered with the default specifications.
CM-0049 - K30 CO2 Sensor Development Kit - 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.
CM-200 - Sensor Development Kit - 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-0049 or CM-200 Development Kit for fastest and easiest results.
