"Vernier"

Measure electrical signals from muscle contractions, or make EKG tracings and surface EMG recordings.

Inexpensive data collection direct to any TI-Nspire® handheld or TI-84 Plus graphing calculator.

Replacement package of 100 electrodes.

Ideal for experiments using UV lamps.

Study Newton's third law.

The CO₂ gas sensor measures gaseous carbon dioxide.

Electronic electroscope to obtain quantitative measurements of charge.

Use this sensor for weather studies, monitoring greenhouses, or for determining days when static electrical discharges could be a problem.

Bidirectional angle sensor.

Use the Turbidity sensor to measure the turbidity of freshwater or seawater samples. Its small, sleek design and simple setup make it easy to use at the collection site or when you return to the classroom.

Measure the concentration of ethanol in air above an aqueous sample.

General-purpose pH Sensors can be used across disciplines, with applications in chemistry, biology, middle school science, and environmental science.

Easily quantify voltage, current, power, and energy output of small wind turbines and solar panels.

Perform accurate, automatic titrations by counting drops of titrant.

Easily collect motion data without the need for additional interfaces.

The High Current Sensor has a range of ±10 A. Current is measured with a Hall Effect sensor, which uses the magnetic field created by the current and therefore does not add a resistive element to the circuit. A metal shield over the Hall Effect chip reduces the influence of external magnets. A replaceable fuse protects the equipment and circuit.
