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,...

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...

Unlike a traditional electroscope, the Charge Sensor can make quantitative measurements. Numerical measurements improve many electrostatics experiments, such as charging by induction, charging by friction, and charging by contact. The...

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...

The Magnetic Field Sensor can be used to study the field around permanent magnets, coils, and electrical devices. It features a rotating sensor tip to measure both transverse and longitudinal magnetic fields. This sensor uses a Hall...

Use the Microphone to display and study the waveforms of sounds from voices and musical instruments. It also works well for speed of sound experiments. Frequency Range: approximately 100 Hz to 15 kHz User manual

The O2 Gas Sensor can be used to monitor gaseous oxygen levels in a variety of biology and chemistry experiments. The sensor is intended for measuring gaseous, not aqueous, O2 concentration. The O2 Gas Sensor measures oxygen...
