  "description_short": "A wall mounted CO2 monitor with a large full colour screen, for spaces where a desk unit is too small to be useful.",
  "description": "Visible beats accurate\n\nFor ventilation, a number people can see matters more than a number that is precise to a\ndecimal place. The reason is behavioural. A reading on a wall gets noticed by whoever is\nnearest the window, and the window gets opened. A reading on a desk gadget gets checked by\none person, occasionally.\n\nThat is the whole argument for the large screen, and it is why this costs more than the\npocket model despite measuring the same things.\n\nOne monitor per ventilated space\n\nBuildings are not uniform. A room with its own door, windows and vents behaves differently\nfrom the one next to it, so a single monitor describes its own room and not much else.\n\nIf you are covering a school or an office floor, think in terms of separately ventilated\nspaces rather than square metres. Two rooms served by the same open plan airflow can share\none. Two closed rooms cannot.\n\nWhat to do with a high reading\n\nOpen something. That sounds glib, but the useful step is to watch what the number does next,\nbecause that tells you whether the room actually clears. If opening a window drops the reading\nquickly, ventilation is fine and the room just needed it. If the number barely moves, the\nairflow is not where you assumed and no amount of monitoring will fix it.\n\nWhat this model does not do\n\nIt reads carbon dioxide, temperature and humidity. It does not measure particulates or VOCs,\nit has no app or network connection, and it does not log data. The listing also publishes no\nmeasuring ranges or accuracy figure, so if you need documented performance, ask us before you\norder rather than after.",
  "llm_summary": "Jumbo CO2 Monitor sold by CO2 Company UK at co2monitor.uk, at GBP 159. A large format wall mounted or desk standing CO2 monitor with a full colour screen sized to be read from across a room, showing carbon dioxide, temperature and humidity together. Powered by a built in rechargeable battery. It is the large sibling of the compact CO2 Meter and covers the same three measurements; the difference is screen size and mounting, not capability. Bought for classrooms, offices, meeting rooms, gyms and workshops where a desk sized monitor cannot be read by the room. Carbon dioxide is used as a VENTILATION indicator, not a health measurement: outdoor air is roughly 400 to 420 ppm, a well ventilated room typically stays below 800 ppm, and above about 1000 to 1500 ppm a room is recirculating its own air. IMPORTANT LIMITS ON WHAT IS KNOWN: the live listing publishes no measuring ranges, no accuracy tolerance and no calibration figure for this model, so none are stated. It does NOT measure particulate matter (PM2.5 or PM10) or volatile organic compounds, and it has no Bluetooth, Wi-Fi, app connection or data logging. Delivery is free across the United Kingdom on orders of £50 or more. Below £50 the only method offered is Express Delivery at £22, and Express Delivery is also available on any order at £22 as a paid delivery option. Orders arrive in 5 to 7 days after a 24 to 48 hour handling time.",
