With this sensor, you can easily monitor changes in CO 2 levels occurring in respiration of organisms ranging from peas to humans. A 250 mL respiration chamber with probe attachment is included for running controlled experiments with...

The Vernier Rotary Motion Sensor is a bidirectional angle sensor designed to measure rotational or linear position, velocity and acceleration. The Rotary Motion Sensor lets you monitor angular motion precisely and easily. It is direction...

The EKG Sensor measures electrical signals produced during muscle contractions, and can be used to make standard 3-lead EKG tracings or surface EMG recordings. The EKG Sensor measures cardiac electrical potential waveforms (voltages...

Il sensore di portata misura la velocità dell'acqua nello studio della portata, del flusso e del trasporto di sedimenti di un torrente o di un fiume. Il sensore di portata può essere utilizzato per studi ambientali o di scienze della...

The Hand-Grip Heart Rate Monitor is ideal for continuously monitoring heart rate before, during, and after exercise or while a person is stationary. The design of the Hand-Grip Heart Rate Monitor makes it easy to monitor heart rate...

Our strain-gauge based isometric Hand Dynamometer can be used to measure grip strength, pinch strength, and to perform muscle fatigue studies. Use the hand dynamometer with other sensors (e.g., EKG Sensor) to study muscular health and...

Designed to collect data on forces developed during stepping, jumping, and other human-scale actions. Designed for much higher forces than the Dual-Range Force Sensor, the Force Plate can measure the forces developed during stepping,...

Use the Dual-Range Force Sensor in a wide variety of experiments, including the study of friction, simple harmonic motion, impact in collisions, or centripetal force. The Dual-Range Force Sensor is a general-purpose sensor for measuring...

The Conductivity Probe determines the ionic content of an aqueous solution by measuring its conductivity. The Conductivity Probe has three ranges, providing optimal precision in any given range. Biology teachers can use this probe to...

Photogates allow for extremely accurate timing of events within physics experiments, for studying free fall, air track collisions, pendulum periods, the speed of a rolling object, among other things. The Vernier Photogate includes an...

The Light Sensor approximates the human eye in spectral response. Use it for inverse square law experiments or for studying polarizers, reflectivity, or solar energy. Typical Resolution: 0–600 lux: 0.2 lux (low) 0–6,000 lux: 2 lux...

Use the Low-g Accelerometer to study one-dimensional acceleration in a wide variety of acceleration experiments and demonstrations. The Low-g Accelerometer is the best choice for most acceleration experiments, including Newton’s second...
