A circuit capable of producing bipolar square pulses of voltages up to +or-400 V, employing an integrated circuit timer and two mercury wetted relays is described. The frequency of the pulses can be varied from a cycle min -1 to 2 kHz. A variable temperature sample chamber and the temperature control and measurement circuits are also described. The performance of the circuit is evaluated using samples of TGS and NaNO 2
