The AJ200 provides an analog answer to your electrochemical needs. There are no computer connections and no menus to navigate. It is a simple instrument for simple applications. Since it is analog in design we can offer you BNC outputs so you can monitor the potential or current output with an oscilloscope, an x-
Most modern potentiostats are designed for computer control from the ground up. Their data are compensated, corrected and improved to provide the “best” answer. That's quite an accomplishment and has provided useful information in many areas. It has its drawbacks. It is expensive. It takes some sense of control away from the operator and it does not give you the true picture of what your analog data looks like. That approach is great for making difficult measurements but what about the majority of measurements that are simple, routine and rather trivial? For those situations you are still forced to pay for the complexity built into the modern potentiostat. That is no longer true!
The AJ200 was designed for the end-
The AJ200 is a simple, analog based potentiostat with current range from 100 nA full-
setting the applied potential and a selector switch to display the value of the applied potential, the measured potential, the current or the external input value. Three BNC connections are provided for Eout, Iout and External Input.
Simple experiments where a potential is applied and current measured can easily be performed. More complex experiments are possible when the user adds a waveform generator, a data acquisition system or an oscilloscope. Since the input and output BNCs are analog the experimenter can see the “true” response of his system to square waves, sine waves, step functions or any new waveform the user can imagine.
The AJ200 is an ideal instrument for teaching purposes, simple experiments and 90% of the electrochemistry done in the lab. What makes it remarkable is that for the first time scientists can acquire this type of instrument without breaking their budget or wasting their experimenting time by building their own potentiostat.
