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 Colorimeter is great for Beer’s law experiments, determining the concentration of unknown solutions, or studying changes in concentration vs. time. This 4-wavelength Colorimeter measures the amount of light transmitted through a...

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...

Der Drei Achsen Beschleunigungssensor wird zur Erfassung komplexer Bewegungen eingesetzt, wie man sie z.B. bei Karussellfahrten oder Bungeesprüngen hat. Mit diesem Sensor sind Sie in den Lehrkapiteln "Schwingung", "Kinematik" und...

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...

The Ethanol Sensor can be used to measure the concentration of ethanol in air above an aqueous sample. This sensor can be used in a wide range of tests and experiments. It can be used to determine the rate of ethanol production during...

The Flow Rate Sensor measures the velocity of water in studying the discharge, flow patterns, and sediment transport of a stream or river. The Flow Rate Sensor can be used for environmental or Earth science studies. Flow rate data can be...

Use the Gas Pressure Sensor to monitor pressure changes of a gas in chemistry and biology experiments. The Gas Pressure Sensor can be used to monitor pressure changes in a gas. The range is wide enough to perform Boyle’s law yet it is...

The Goniometer measures the angle of a joint, such as the knee or elbow. Use it to analyze the range of motion of a limb during different types of physical activity. A set of elastic straps are used to secure the sensor to the subject....

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...

Use the Ammonium ISE to measure levels of ammonium ions introduced from fertilizers. It can also indicate aqueous ammonia levels if sample solutions are acidified to convert NH 3 to NH 4 + . The Ammonium ISE has a combination-style,...
