A simple and cheap AC voltammeter was manufactured in our lab. This instrument consists of a DC function generator and a lock-in amplifier. We tested this instrument in some chemical systems. Our data, CV voltammogram and AC voltammogram, obtained form using a Pt working electrode in 1M <TEX>$H_2SO_4$</TEX> and a reversible system of <TEX>$1{\times}10^{-3}M$</TEX> <TEX>${Fe(CN)_6}^{3-}$</TEX> proved our system works well. The quantitative result of iodine is also obtained.
