Autopilot APCEM2 Hydroponic CO2 RH Temperature Monitor and Data Logger (2 Pack)

Monitoring stats like carbon dioxide, temperature, and humidity are imperative to growing healthy, strong plants with a hydroponics system. Help keep those levels in check with the Autopilot Desktop CO2 Monitor and Data Logger. This monitor features a digital memory chart that shows and records stats over an adjustable 24 hour or 7 day period. It has an audible alarm for low or high CO2 levels and a light that indicates if it's on target. View the charts from a weekly, daily, hourly, or per minute view.
