POTENTIOSTAT / GALVANOSTAT

WENKING
The TG 97 Laboratory Potentiostat is an economically priced instrument for standard
electrochemical applications in many fields of investigation. It replaces our predecessor
model LT 87.
The medium power output of 20 W will be sufficient for most laboratory work. The TG
97 can be switched from the potentiostatic mode to the galvanostatic mode by the
operation switch. The current resolution reaches down to the nA range. The grounded
working electrode principle keeps the sensitivity to noise-pickup low.

• Small, but Powerful: ± 20 V at ± 1 A
• Easy to Operate
• Potentiostatic / Galvanostatic Function
The internal control voltage source operates from -2 to 2 V. An external control voltage can be
superimposed in the range ± 10 V. All our auxiliary equipment fits this potentiostat.
Both the low-impedance potential output and the current output refer to ground. The current signal level
of 2 V per full range current is well adapted for A/D - conversion.
The TG 97 is easy to operate. It is safeguarded against operating errors. Inputs are protected against
overvoltages up to 100 V. Output voltage overload is indicated by signal lamps. The output current is
limited slightly above 1 A, so short - circuits in the cell do not affect the instrument.
Working electrode and counter electrode are connected by standard banana terminals, the reference
electrode by a BNC - connector. The working electrode can be connected by two separate cables, thus
avoiding errors by cable and contact resistances of the current conductor.
