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,...

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...

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...

The PAR (Photosynthetically Active Radiation) Sensor reports the Photosynthetic Photon Flux Density (PPFD), which corresponds to micromoles of photons per meter squared per second (μmol m-2 s-1). This is the power of electromagnetic...

Our general-purpose pH Sensor can be used across disciplines, including chemistry, biology, middle school science, and environmental science. Use the pH Sensor just as you would a traditional pH meter with the additional advantages of...

Use the Tris-Compatible Flat pH Sensor to measure the pH of a solution or semisolid, such as food or soil. The Tris-Compatible Flat pH Sensor is a highly versatile sensor. Because the glass membrane is flat instead of a bulb, it is more...

The Oxidation-Reduction Potential (ORP) Sensor measures the ability of a solution to act as an oxidizing or reducing agent. Use the ORP Sensor to measure the oxidizing ability of chlorine in swimming pools or to determine when the...

The Salinity Sensor precisely measures the total dissolved salt content of ocean or brackish water. The Salinity Sensor easily and precisely measures the total dissolved salt content in an aqueous solution. Measure water with a wide...
