Model 1200C Series Computerized Hand-Held Potentiostat/Bipotentiostat

By CH Instruments

The Model 1200C series is a computerized hand-held potentiostat/bipotentiostat. The instrument contains a digital function generator, a data acquisition system, and a potentiostat/bipotentiostat, and it is well suited for electroanalysis and sensor studies. The potential range is ±2.4 V, and the current range is ±2 mA. This series is capable of measuring current down to 100 pA. The steady state current of a 10 μm disk electrode can be readily measured. The size of the instrument is 7” (L) x 4.5” (W) x 1” (H). The instrument is powered by the USB port of an external computer, without the need for an AC adapter or batteries. Due to its small size, light weight, and low cost, it is particularly useful for field applications and teaching laboratories. The Model 1200C series allows ±7.5 V compliance voltage, which ensures its working potential range of ±2.4 V for most electrochemical systems. It also uses dual 16-bit DAC and 16-bit ADC for high resolution and accuracy. The instrument provides many powerful functions, such as straightforward file handling, extensive experimental control, flexible graphics, various data analysis, and efficient digital simulation. Some of the unique features include macro commands, working electrode conditioning, color, legend and font selection, data interpolation, visual baseline correction, data point removal, visual data point modification, signal averaging, Fourier spectrum, and equations relating to electrochemical techniques. The 1200C series provides various instrument models to meet different applications and budgets. The series is available in potentiostat (1200C, 1210C, 1220C, 1232C, and 1240C) and bipotentiostat versions (1202C, 1212C, 1222C, 1232C and 1242C).
