CO2 Sensoren
CozIR®-Blink
Zero power consumption when not taking measurements!
The CozIR®-Blink is an ultra-low power NDIR CO2 sensor using state-of-the-art solid-state LED optical technology. The low-power LEDs are manufactured in-house, giving GSS complete control of the CO2 sensor signal chain.
The CozIR®-Blink uniquely allows users to reduce the power consumption of CO2 measurements to unprecedented levels. The CO2 sensor can be power-cycled, allowing the user to wake-up the unit from a dormant state, take a reading, and then power it down completely again, reducing power consumption to zero. The power cycling function is particularly valuable in battery-powered or wirelessly connected interface applications where power is at a premium.
The CozIR®-Blink also features a built-in auto-calibration function that maintains CO2 measurement accuracy over the lifetime of the product.
