Sensor Specifications Description
Hand-Grip Heart Rate Monitor HGH-BTA The Hand-Grip Heart Rate Monitor measures a person’s heart rate by registering the
small electrical signals carried across the surface of a person’s skin each time his or her heart contracts. This signal is measured at the surface of the skin by electrodes embedded in the hand grips of the Hand-Grip Heart Rate Monitor. By graphing this signal, the heart rate can be determined.
Hand Dynamometer HD-BTA The strain-gauge based isometric Hand Dynamometer can be used to measure grip strength, pinch strength, and to perform muscle fatigue studies. The Hand Dynamometer can be used alone or in combination with EMG recordings for detailed studies of muscular activity. Measurements can be made in Newtons or kilograms force. This sensor can be used alone or in combination with other sensors (e.g., EKG Sensor) for studies of muscular health and activity.
O2 Gas Sensor O2-BTA The Vernier O2 Gas Sensor is used to monitor gaseous oxygen levels in a variety of biology and chemistry experiments. The sensor is intended only for measuring gaseous, not aqueous, O2 concentration.
Surface Temperature Sensor STS-BTA The Surface Temperature Sensor is designed for use in situations in which low thermal mass or flexibility is required. Special features include an exposed thermistor that results in an extremely rapid response time.
EKG Sensor EKG-BTA The Vernier EKG (Electrocardiogram or ECG) Sensor measures electrical signals produced during muscle contractions. It can be used for standard 3-lead EKG tracings or to make surface EMG recordings. Each of the three leads on the sensor connect to disposable electrodes. Above, an EKG graph is displayed, demonstrating to students the contraction and repolarization of the heart's chambers. A package of 100 disposable electrodes is included with the sensor.
Blood Pressure Sensor BPS-BTA The Blood Pressure Sensor is a non-invasive sensor designed to measure human blood pressure. It can be used to measure systolic and diastolic blood pressure utilizing the oscillometric technique. The sensor includes a standard adult size adjustable cuff (27 cm to 39 cm), pump bulb and pressure transducer.  A smaller cuff (18 cm to 27 cm) is available for younger students, and includes a pump bulb and valve.
Spirometer SPR-BTA The Spirometer can be used to perform variety of tests related to air flow and lung volume. The sensor includes a removable flow head (22 mm ID/30 mm OD) for easy cleaning and sterilization, and a differential pressure transducer. The Spirometer is designed to make human respiratory measurements at rest and during moderate activity. The Spirometer package includes 1 sensor handle, 1 flow head, 5 disposable mouthpieces, 1 disposable bacterial filter, and 2 nose clips.
Analog Proto Board Connector BTA-ELV This connector allows the use of Vernier analog BTA sensors on National Instruments ELVIS prototyping boards

bp sensor vi not present  - Feb 3, 2015

the main compicated programming among these sensors is blood pressure measurement. sadly there is no bp sensor vi .. kindly add that to support us students.

Hello there, i found a problem as i cant extract all of the file contents in the zip folder because some of the file path and files name length are too long (already exceed 260 characters) hopefully this issue will be solved.
