FARADAY PRO PRECISION SCANNING POTENTIOSTAT |
Host Connection - Faraday Pro connects to the host computer via the
USB port. The USB serial interface engine is driven by USB power, whereas electrochemical
power is generated by the main instrument power supply, reducing the amount
of computer generated noise on the electrodes.

User-friendly Software - The Faraday Pro system was designed for primary use in academic research laboratories. All buttons and parameter readouts are thoughtfully positioned, clearly labeled, and supplemented with tool-tips.
iR Compensation - Automated software iR compensation eliminates the need for expensive specially designed cells and high electrolyte concentrations.
Software Noise Reduction - The electronics of Faraday Pro includes selectable hardware filtering circuitry. In addition, the filtration circuitry can be bypassed, replaced by an antialiasing filter, and noise reduction can be taken over by sophisitcated Fourier transform routines in the software. Thus, the raw signal over the entire bandwidth is transmitted to the host computer eliminating any inadvertent alteration of the data due to inappropriate hardware filtering. Noise reduction and/or signal enhancement is then performed in software via signal averaging or by the Fourier transform algorithms. Hence the user has complete control over the type and amount of noise reduction, enabling even very weak signals to be safely extracted in noisy environments.
Portability - Faraday Pro interfaces with the host computer via the USB port. No additional interface cards, data acquisition cards, or special cables are required, and no hardware modifications to the computer are needed.
