application in identifying areas of peak and low amplitude
in interference, reflection and refraction experiments. There
are two controls, one for sensitivity and the other for volume
of output to the internal loudspeaker. Power is from the
same type of plug-top supply as used by the receiver unit
(above). An additional power supply unit can be supplied
if requested. Probe detector 130 x 80 x 130 mm high.
