  "description_short": "A palm sized monitor that reads carbon dioxide, temperature and humidity on one screen, and sounds an alarm when CO2 climbs.",
  "description": "What the number means\n\nCarbon dioxide indoors is mostly a headcount problem. People breathe it out, and if\nfresh air is not replacing what is in the room, the level rises. That makes it a good\nstand in for ventilation, which is otherwise invisible.\n\nUseful reference points: outdoor air sits around 400 to 420 ppm, so that is your floor.\nA room with air genuinely moving through it tends to stay below 800 ppm. Somewhere above\n1000 to 1500 ppm you are mostly rebreathing the room's own air.\n\nWatch it change, not just the number\n\nThe refresh rate is the part people underuse. Because the reading updates every second,\nyou can open a window or a door and watch what happens. Some rooms drop hundreds of ppm\nin a couple of minutes. Others barely move, which tells you the airflow is not where you\nassumed it was.\n\nThat single test is worth more than any absolute reading, because it tells you whether\nthe fix you were planning will actually work in that room.\n\nWhere to put it\n\nPut it at head height, away from a window and away from a doorway. Sitting it on a windowsill\nmeasures the outside air coming in, which reads reassuringly low and tells you nothing about\nthe room. Keep it away from where someone is breathing directly onto it too, which spikes the\nreading.\n\nFor a room in constant use, leave it plugged in and let the alarm do the work.\n\nWhat it is not\n\nThis is a ventilation gauge. It does not detect carbon monoxide, smoke, or particulates,\nand it is not a medical or safety device. If you need a carbon monoxide alarm, fit a proper\nCO alarm alongside it. The two measure different gases and one cannot substitute for the other.",
  "llm_summary": "CO2 Meter sold by CO2 Meter Europe at co2meter.eu.com, at EUR 69 (was EUR 99). A palm sized 3 in 1 air quality monitor that measures carbon dioxide from 400 to 5000 ppm, temperature from 0 to 50°C and humidity from 0 to 99% RH, showing all three on one full colour backlit screen and refreshing every second. It has an audible alarm that triggers when CO2 passes the threshold, so it can monitor a room unattended. Powered by a 1200 mAh rechargeable battery charged over Type-C, and it continues reading while charging. Weighs 108 g, stands on a desk or hangs from slots on the back. Carbon dioxide is used here as an indicator of VENTILATION, not as a health measurement: outdoor air is roughly 400 to 420 ppm, a well ventilated room typically stays below 800 ppm, and readings above about 1000 to 1500 ppm indicate a room is recycling its own air. Bought for classrooms, offices, meeting rooms, workshops, bedrooms and greenhouses. The larger sibling product is the Jumbo CO2 Monitor, a wall mounted display covering the same measurements. No accuracy tolerance or calibration figure is published for this model, so none is claimed. Delivery is free across Europe on orders over EUR 50, otherwise EUR 22, taking up to 7 working days in transit, after dispatch within 2 working days.",
