The Polarimeter can be used to measure chiral properties of optically active samples without chemically modifying or destroying the sample. This is a vertical polarimeter that uses a 589 nm LED, a fixed polarizer, and a manually rotated polarizer to detect changes in rotation of plane-polarized light in the presence of an optically active compound. Used with Vernier technology, students no longer have to determine the optical maximum with their eye but have a graph that shows a clear change in the light's polarization.

The Vernier Energy Sensor offers an easy way to quantify voltage, current, power, and energy output of small wind turbines and solar panels such as those used in our KidWind Experiment Kits. Simply connect a source such as a small wind turbine or solar panel to one side and a load such as the Variable Load or a resistor on the Vernier Resistor Board to the other side. The Energy Sensor measures the current and voltage of the system. Data-collection and analysis software, such as Logger Pro or LabQuest App can then calculate the power and energy output.

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 has two ranges: ±10N or ±50N. It can be easily mounted on a Vernier Dynamics Cart for use with the Vernier Dynamics System. Mount one on the New Centripetal Force Apparatus, on a ring stand or even as a replacement for a hand-held spring scale. Use it to study friction, simple harmonic motion, impact in collisions, or centripetal force.

The Gas Pressure Sensor can be used to monitor pressure changes in a gas. The range is wide enough to perform Boyle's law yet it is sensitive enough to conduct vapor-pressure or pressure-temperature experiments. Biology teachers can use the Gas Pressure Sensor to monitor transpiration or respiration in an enclosed environment.

The Instrumentation Amplifier monitors voltages from 20 mV to 1 V (DC or AC). It has several switch settings to allow you to select the best gain and includes auto-ID functionality for each of the six ranges. Input bandwidth of 10 kHz allows the capture of higher frequency signals. It is typically used to amplify the chart recorder or analog output of any instrument, such as a third-party gas chromatograph.
