Grow Tools CO2 Monitor – Digital CO2 Monitoring Device

See CO2, Temperature and Humidity at a Glance

The Grow Tools CO2 Monitor combines a carbon dioxide readout with temperature and relative humidity monitoring in one small, rechargeable unit, so you get all three numbers on a single colour display instead of juggling separate gauges. Running a room on guesswork wastes CO2 supplementation when levels are already adequate, or leaves plants short of it when they would benefit most - a live reading takes the guesswork out, and a colour-coded ring around the display makes it obvious at a glance whether levels need attention.

Key Benefits

• Three readings in one unit - CO2, temperature and humidity
• Colour-coded display shows at a glance whether CO2 is low, adequate or high
• 1-second refresh rate for fast, responsive readings
• Rechargeable battery - no disposables to keep replacing
• Compact and portable - move it between tents or rooms as needed

How to Use

• Charge the unit fully before first use.
• Position it at canopy height, away from direct extraction airflow, for a representative reading.
• Check the display regularly and use it alongside your CO2 supplementation (gas bottle, bag or generator) to judge when levels are adequate.
• Keep the vents clear of dust so the sensor keeps reading accurately.
