Constant Current System > Vernier Software & Technology

Recommended for College and High School. Interface and software sold separately.

The Constant Current System is a DC power source with a built-in current probe designed for use in electrochemistry experiments.


The Constant Current System eliminates the need for a separate power supply when performing electroplating and electrolysis experiments in chemistry. It is capable of delivering up to 0.6 A at 5 V DC.

A current-sensing resistor allows monitoring of the output current through the sensor cable. The user can set the current by tuning the dial with the system automatically adjusting the voltage.

Use the Constant Current System to explore Faraday’s law and determine Avogadro’s Number.

Note that it can only be used in conjunction with its own built-in power supply—it cannot be used to measure the current of a circuit using a different power supply.

SpectroVis Plus Spectrophotometer > Vernier Software & Technology

With its two different excitation wavelengths, SpectroVis Plus can quantitatively measure the fluorescence spectra of many compounds, such as chlorophyll, fluorescein, GFP, and more. Emerging light goes through a high-quality diffraction grating, then the diffracted light is collected and sorted by the CCD array detector. SpectroVis Plus is an affordable, portable, visible to near-IR spectrophotometer and fluorometer.
