(Order Code GDX-CO2)
Go Direct CO
Gas measures carbon dioxide concentration, temperature, and
2
relative humidity. This sensor includes built-in temperature compensation and
humidity protection. A 250 mL Nalgene bottle is included for running controlled
experiments with small plants and animals.
Go Direct CO
Gas is ideal for the following experiments:

Study the effect of temperature on cell respiration or metabolism of organisms.
l
Study how yeast metabolize different sugars.
l
Investigate artificial selection by comparing respiration rates of different yeast
l
strains.

Blue LED is off when charging is complete.
Press button once. Red LED indicator flashes
when unit is on.
Press and hold button for more than three seconds
to put into sleep mode. Red LED indicator stops
