World's Fastest Battery-Powered NDIR CO2 Sensor Debuts At Sensors Expo

At Sensors Expo 2017, San Jose, CA in booth 922, Gas Sensing Solutions (GSS) Ltd. will be demonstrating its new, ultra-fast SprintIR6S.  The company’s unique SmartIR technology has enabled it to create a sensor that can take up to 20 readings per second, with a six times faster response rate than the current SprintIR* due to it having a sample volume of only 2ml.  The SprintIR6S is available to measure CO2 concentrations right up to 100%, providing a cost-effective solution for high concentration monitoring that previously needed very expensive detectors. The ultra-fast response is particularly relevant in industrial applications to monitor that the correct, high levels of CO2 are being used.

 

At less than a cubic inch (23.8mm in diameter and 24mm tall), the SprintIR6S operates between 3.25 and 5.5V with a power consumption of only 35mW.  The SprintIR6S is available in measurement ranges from 0-100%.

SmartIR technology monitors the presence of CO2 by detecting how much light is absorbed by CO2 molecules as light passes through the sample gases - called Non-Dispersive InfraRed (NDIR) absorption.  CO2 absorbs between 4.2 and 4.4 microns and the amount of light absorbed indicates how much CO2 is present.  Typical CO2 detectors use a heated filament to generate a range of wavelengths in the InfraRed (IR). This is very energy inefficient as the light has to be filtered to leave the required wavelengths, and a lot of waste heat is also produced. By contrast, GSS developed the world's first commercial, mid-range IR LEDs that are specifically tuned to emit between 4.2 and 4.4 microns, making them highly energy efficient.
