VERNIER GO DIRECT EKG SENSOR
The Vernier Go Direct EKG Sensor measures electrical activity in the heart and electrical signals produced during muscle contractions. The wireless options minimize the concern of cables getting caught and tangled during experiments. This sensor provides two separate outputs: one optimized for standard 3-lead EKG tracings and one optimized for surface EMG recordings. EMG recordings can also be rectified automatically by the sensor.

The Vernier Go Direct EKG Sensor can be used in a variety of experiments:
• Compare and measure students’ electrocardiogram (EKG/ECG) waveforms.
• Determine heart rate by examining the number of QRS waveforms in a series of electrocardiograms (EKG/ECGs).
• Study contractions of muscles (EMG) in the arm, leg or jaw.
• Correlate measurements of grip strength and electrical activity with muscle fatigue.

Rechargeable Battery — Ready When You Are
The Vernier Go Direct™ robust rechargeable battery offers long battery life and provides always-ready operation. Monitor battery life directly from Vernier's free Graphical Analysis™ 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
Vernier's Go Direct™ sensors connect directly to your mobile device, Chromebook or computer using Vernier's free Graphical Analysis™ app. No additional equipment or software purchases are necessary. Vernier Go Direct sensors can be used wired via USB or wirelessly via Bluetooth allowing you to choose the solution best for your classroom or laboratory.

GAPRO Vernier Graphical Analysis™ Pro includes all the features of the free Vernier Graphical Analysis app, plus enhanced functions for more advanced analysis. Its illustrative experiment videos and interactive graphing capabilities inspire students to explore crucial scientific concepts and analyze data in new complex and insightful ways.
GAPRO is compatible with most Vernier sensors and multiple operating systems and devices.

  This product is used in teaching these Australian Curriculum codes:
  ACSBL115 - Maintaining the internal environment - Homeostasis - Animals, whether osmo-regulators or osmo-conformers, and plants, have various mechanisms to maintain water balance that involve structural features, and behavioural, physiological and homeostatic responses
  ACSBL111 - Maintaining the internal environment - Homeostasis - Changes in an organism’s metabolic activity, in addition to structural features and changes in physiological processes and behaviour, enable the organism to maintain its internal environment within tolerance limits
  ACSBL110 - Maintaining the internal environment - Homeostasis - Homeostasis involves a stimulus response model in which change in external or internal environmental conditions is detected and appropriate responses occur via negative feedback; in vertebrates, receptors and effectors are linked via a control centre by n
  ACSSU150 - Biological Sciences - Organ Systems - Multi-cellular organisms contain systems of organs that carry out specialised functions that enable them to survive and reproduce
  ACSSU175 - Biological Sciences - Organ Systems - Multi-cellular organisms rely on coordinated and interdependent internal systems to respond to changes to their environment
