CO2 Sensors Are Highly Sensitive, Low On Power

Targeting the growing market of CO2 refrigeration systems, Gas Sensing Solutions’ ExplorIR-W CO2 sensors sport a robust design. They are built with mid-infrared LED technology at their core. It's this solid-state technology that enables the earliest warning of any possible CO2 leaks. This also provides the required long lifetime and high precision needed in leak detection applications.


Available with an extended temperature range, the ExplorIR-W can operate reliably down to -25ºC as required in many supermarket freezers. It is available in measurement ranges of 0 to 5%, 0 to 20%, and 0 to 100% CO2 concentrations according to the specific application. The sensor can be adapted for special requirements or developed into a custom CO2 sensor solution for leak detection applications.

New VNA technologies enable mmWave broadband testing to 220 GHz, helping researchers and engineers to overcome test challenges and simplify mmWave testing.

Application development in the mmWave frequencies is growing. Broadband testing over hundreds of GHz of bandwidth is subject to repeatability/accuracy deficits, and engineers demand solutions to help overcome challenges and simplify mmWave testing.


The company’s CO2 sensors work by measuring how much light is absorbed by CO2 molecules in the 4.2 and 4.4 microns range as it passes through the sample gases, which is called Non-Dispersive Infra-Red (NDIR) absorption. The amount of absorption indicates how much CO2 is present. Gas Sensing Solutions developed proprietary LEDs that are specifically tuned to emit at these wavelengths. The LEDs use very little power and turn on almost instantly, enabling sensor readings to be made in less than a second. Learn more about the company’s LED technology.
