High f r e q u e n c y Energy

ULTRA-S0N0RAT0R, Senior Model The Ultra-Sonorator transforms electrical energy from any 110 volt, 50-60 cycle A.C. line to about 500 watts of radio-frequency energy that can be applied to the material under study. The frequencies attainable with the Senior Model include 400 kc., 700 k c , 1000 kc. and 1500 kc. Frequency changing is accomplished by switching transducer j a r s ; all four furnished are equipped with polar­ ized plugs which select the corresponding frequency in the generator unit.

Model

The Table Model Ultra-Sonorator, left, is designed primarily for experiments at the single frequency (400 kc.) deemed suitable for initial work in ultrasonics. Using 110 volt, · 50-60 cycle A.C, about 500 watts of r a d i o - f r e q u e n c y energy are delivered through the transducer crystal. The complete Table Model consists of two units : one unit housing the generator and controls, the second unit holds the crystalbath assembly in place. Price, complete, $1,075.00
