The function of constant current source is to supply constant working current for the chemically-regenerated suppressor of ion chromatography of thermo fisher and to control the concentration of the solution of elution. The accommodation mode of constant current source is many laps potentiometer（1mA step）.The LED displays the current value.

The following types of suppressor can use this constant current source：

AERS500

CERS500

ASRS300
