Go Direct® Spirometer

Go Direct Spirometer is designed to make human respiratory measurements easy.

SKU: GDX-SPR Categories: , ,


Designed with the classroom in mind, the small, lightweight design of Go Direct Spirometer makes it an excellent choice for human physiology classes. This is a multi-channel sensor that reports air pressure, flow rate, volume, and respiration rate. Measuring tidal volumes and other lung function parameters are both simple and easy due to channels that automatically adjust for baseline drift. With both USB and wireless capabilities, students can monitor human respiratory patterns anywhere using any compatible device.

The flow head is not designed to be removed or sterilized by the user. A bacterial filter and mouthpiece are required for use. The flow head can be replaced to maximize the life of the product.

Go Direct Spirometer can be used in a variety of experiments:

  • Compare and analyze respiratory patterns.
  • Measure tidal volume and other lung volume parameters.
  • Analyze lung function.

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 free Graphical Analysis 4 app or LabQuest 3 App. 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.

Wired or Wireless—The Flexibility to Choose

Our Go Direct sensors connect directly to your mobile device, Chromebook, or computer using our free Graphical Analysis 4 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 solution best for your classroom or laboratory.
