If you enrich with CO2, the opposite risk applies: levels can climb too high for people working in the room. A monitor with an alarm shows you which side of the line you are on, and whether your extraction or CO2 supply needs adjusting.\u003c\/p\u003e\u003ch3\u003eHow to Use\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePlace the monitor at canopy height, away from direct airflow from fans or CO2 outlets.\u003c\/li\u003e\n\u003cli\u003ePower it by USB from the supplied mains adaptor, a PC or a USB power bank.\u003c\/li\u003e\n\u003cli\u003eSet the alarm threshold and backlight colours following the supplied instructions.\u003c\/li\u003e\n\u003cli\u003eCheck the 24-hour chart to see how CO2 changes between lights-on and lights-off.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\u003cdiv class=\"hcs-specs\"\u003e\u003cul\u003e\n\u003cli\u003eSensor: NDIR (Non-Dispersive Infrared) CO2\u003c\/li\u003e\n\u003cli\u003eDisplays: CO2 (ppm), temperature, relative humidity, clock, 24-hour CO2 bar chart\u003c\/li\u003e\n\u003cli\u003eBacklight: green \/ amber \/ red CO2 indication, seven selectable colours, auto-dim 22:00–06:00 or off\u003c\/li\u003e\n\u003cli\u003eAlarm: programmable audible alarm at a user-set CO2 level\u003c\/li\u003e\n\u003cli\u003ePower: USB, mains adaptor supplied (or PC \/ USB power bank)\u003c\/li\u003e\n\u003c\/ul\u003e\u003c\/div\u003e","brand":"Essentials","offers":[{"title":"Default Title","offer_id":53803798298890,"sku":"TLS-ESS-002-01","price":97.9,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0748\/7127\/5786\/files\/essentials-co2-monitor-1.jpg?v=1790229471","url":"https:\/\/hydrocropshop.co.uk\/products\/essentials-co2-monitor","provider":"Hydro Crop Shop","version":"1.0","type":"link"}
