Hello!! I am writing to inquire about the detection limits and specifications of the purple air sensors.
We have been observing some unexpected readings from our monitors, including values as low as 0 ppm and others as high as 3000 ppm, which seem unlikely. To better understand and address these discrepancies, we would like to confirm the specific detection limits and performance parameters of the sensors.
