Other Electrodes

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

The soil moisture sensor is used to measure the volumetric water content of soil. This makes it ideal for performing experiments in courses such as soil science, agricultural science, environmental science, horticulture, botany, and biology.

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

The CO₂ gas sensor measures gaseous carbon dioxide.

Study Newton's third law.

Bidirectional angle sensor.

Secure your Go Direct® sensors for field work.

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.

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.
