Industrial / Wide Range
CO2 Sensors

Industrial applications often require rugged, high performance CO2 sensors which can measure high levels of CO2 gases.  GSS provides CO2 sensors for concentrations as high as 100%. 

Based on the reliable and proven SmartIR technology, these NDIR sensors deliver best in class performance, while retaining the ruggedness and low power attributes that come from being based on a solid-state (LED) technology.

MinIR A tough CO2 sensor with ranges from 0-5% right through to 0-100%, MinIR is a miniaturised and rugged sensor for industrial environments. SmartIR 3
CozIR/W A versatile CO2 sensor covering a wide range and with the options of voltage output, and both Temperature and Relative Humidity capability SmartIR 3

(For breathable air environments, please see our Ambient/Breathable Air CO2 sensor range; we also have a range of high speed NDIR CO2 sensors)


Based on GSS's patented SmartIR technology, the MinIR uses robust solid state technology, which is vibration-proof and capable of handling wide variations in pressure. That makes it an ideal choice for industrial applications, as well as aerospace, diving and other harsh environments.  The MinIR also boasts the industry's lowest power consumption.  

SmartIR sensors are easy to design with - our pedigree in low power and IoT sensing applications means that we've been able to eliminate many of the system-level challenges in developing sensor applications.  For example, reduced pulse currents eliminate the requirement for super-capacitors in battery powered designs, while the low power dissipation nullifies the self-heating effect which plagues designs which integrate temperature sensing.

With many years of experience delivering CO2 sensors to some of the world's biggest manufacturing companies, you can be sure that a MinIR sensor from GSS is the reliable choice for your application.
