Radio-controlled apparatus for automatic analytical measurements.
An apparatus is described for remote control of chemical operations and for remote monitoring of processes, by means of a radio-receiver tuned to the initial frequency of an oscillator that transduces some physical parameter of the system monitored. The receiver operates a relay (with feed-back to the system) when the emitted frequency changes as a result of a change in the system examined.
