The Go Direct Respiration Belt measures human respiration rate. It connects via Bluetooth® wireless technology or via USB to your device.

SKU: GDX-RB Categories: , ,


Measure human breathing patterns quickly with the Go Direct Respiration Belt, which connects wirelessly via Bluetooth® or wired via USB to your device. Go Direct Respiration Belt uses a force sensor and an adjustable nylon strap around the chest to measure respiration effort and respiration rate. An LED indicator provides feedback so belt tension can be optimized. Respiration rate is reported in the Graphical Analysis 4 app, which makes comparison studies between subjects or experiments easy to do.

  • Observe how respiration rate changes after exercise or breath holding.
  • Observe how respiration effort (the force exerted by the chest during respiration) changes after exercise or breath holding.
  • Measure steps and step rate during a study with the built-in pedometer.

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.
