Examine how objects move, accelerate and swing. This sensor and pendulum accessory help students explore topics such as the effects of gravity on objects in motion.

The Salinity sensor is designed to measure the salinity of liquids and solutions and is capable of measuring the entire range of 24-52,000 ppm (parts per million). Salinity is one of the most basic tests conducted in solutions. It determines the total concentration of salts in a sample.

Measure the velocity and acceleration of moving objects, learn Newton’s laws of dynamics, or Newton’s second law with this Smart Pulley.

Our sodium sensor easily measures the amount of sodium in a solution. Use the sodium sensor for Agriculture studies, experiments on food and Chemistry studies.

Measure the soil moisture’s electric resistance and convert data into calibrated readings of soil water suction.

Use the sound sensor to Investigate environmental noises, room acoustics, sound level or sound isolation.

The Spirometer is a breathing sensor designed to conduct physiology experiments. Based on air speed, the Spirometer calculates the airflow rate and lung capacity of a subject who is breathing into the sensor.

This all-purpose temperature sensor with a range of -40° to 140°C is particularly well suited for conducting water and other chemical solution temperature measurements.

This Platinum Resistance Thermometer (PRT) is ideal for use in the research of extremely low temperatures and it is also a very powerful sensor for monitoring liquid gases and other materials.

This high accuracy Surface Temperature Sensor enables exploration of topics such as skin temperature measurements and the effects of wearing light or dark-colored clothing in the sun.

The Thermocouple sensor can be used in high temperature experiments such as monitoring chemical processes that occur in high temperatures, measuring the different temperatures in a flame or simply monitoring ovens.

This sensor measures the cloudiness of water due to industrial processes or environmental pollution.

Study the UV variations along a fluorescent tube, the invisible light from different sources or fluorescent rocks and dyes.

This broad range voltage sensor can measure direct and alternate voltage current, EMF and internal resistance, V-I characteristics of a wire, a light bulb and a diode, connections of batteries, resistance of a wire or Ohm’s Law.

This low range sensor can measure direct and alternate voltage current, EMF and internal resistance, V-I characteristics of a wire, a light bulb and a diode, connections of batteries, resistance of a wire or Ohm’s Law.

This medium range sensor can measure direct and alternate voltage current, EMF and internal resistance, V-I characteristics of a wire, a light bulb and a diode, connections of batteries, resistance of a wire or Ohm’s Law.

When measuring alternating voltage, this sensor measures the voltage, squares the values and then uses the square root of the results to determine the true measurement. This True Root Mean Square (TRMS) reading is considered the most accurate way of measuring voltage.
