CozIR® Serie
CozIR®-LP3
The CozIR®-LP3 is a low power NDIR CO2 sensor using state-of-the-art solid-state LED optical technology. The low power LEDs are manufactured in-house, giving Gas Sensing complete control of the CO2 sensor signal chain.
The CozIR®-LP3’s low power consumption is compatible with battery powered operation, allowing the sensor to be used in a wide variety of applications including wirelessly connected equipment. The CozIR®-LP3 operation is configurable depending on user requirements. On powerup, the CozIR®-LP3 automatically starts taking measurements. Measurements can be streamed or output on request. The CozIR®-LP3 also features a built-in autozero function that maintains CO2 measurement accuracy over the lifetime of the product.
