Go Direct® CO2 Gas Sensor

$225.00

The Go Direct CO2 Gas Sensor measures gaseous carbon dioxide concentration levels, air temperature, and relative humidity. It can be used in a variety of biology experiments. It connects via Bluetooth® wireless technology or via USB to your device.

ORDER CODE: GDX-CO2 Categories ,

Monitor changes in carbon dioxide, temperature, and relative humidity easily with the Go Direct CO2 Gas Sensor. 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.

The Go Direct CO2 Gas Sensor is ideal for the following experiments:

  • Measure the change in gas concentration during cellular respiration.
  • Measure the change in gas concentration during photosynthesis.
  • Study the effect of temperature on cell respiration or metabolism of organisms.
  • Investigate artificial selection in yeast by comparing respiration rates of different strains.

Rechargeable Battery—Ready When You Are

The robust rechargeable battery offers long battery life and provides always-ready operation when using the sensor wirelessly. Monitor battery life directly from our award-winning Vernier Graphical Analysis® app, as well as LabQuest® 3. Should the battery run low, simply connect the sensor to the charging cable and keep on collecting—no interruptions or inconvenience to you or your students.

Wireless or Wired—The Flexibility to Choose

Our Go Direct sensors connect directly to your mobile device, Chromebook™, or computer using our Vernier Graphical Analysis® app—no additional equipment or software purchases are necessary. Go Direct sensors can be used wired via USB or wirelessly via Bluetooth® wireless technology, allowing you to choose the best solution for your classroom or laboratory.
