An “electronic load device” is a device that uses semiconductors such as transistors instead of variable
resistors. The electronic load device that uses semiconductors can freely change the current and
voltage, so it can be used as a variety of loads by incorporating a control circuit.

Potentialstat / galvanostat PS-06 when combined with an XY recorder becomes a cyclic voltammetry or
automatic polarization device.

Temperature humidity chambers (also known as climatic or climate test chambers) simulate the effects
that a range of temperature and humidity conditions have on a sample.
