AG700 is a 3 in 1 Desktop CO2 Monitor measures the indoor air quality index, including the CO2, TEMP, and RH. By using Dual Beam NDIR technology, it provide accurate CO2 readings ranging from 0 to 5000 ppm. It has Human and plant modes built in.
In human mode, it is useful in verifying indoor air quality for home, office, school, restaurant, library, station, or vehicle interior.
In plant mode, it is a guardian for users to control CO2 level in greenhouses or hydroponics to achieve the goal of efficient plant growth and increase yield.

LCD Display:
The trend chart (1) displays the past readings for any of the three parameters (CO2/Temp/RH). There are 4 modes that can be toggled by using UP key: CO2, TEMP, RH, and Cycle (automatically cycles through CO2/Temp/RH), as shown below

Trend Chart Zoom:
Below is a table that show the available Zoom Levels for all parameters CO2/Temp/RH, as well as the duration of each division for corresponding Zoom Levels:

CRR Function:
Predicts the remaining CO2 supply and reminds the user to add or replace the CO2 generator. For example, hydrocarbon fuel, fermentation (sugar + yeast), etc.
