Zusammenfassung:A DEVICE FOR REMOTELY CALIBRATING LEAK SENSORS. A SUPPLY OF LIQUID ANALYTE CALIBRANT IS STORED IN A RESERVOIR, AND IS COMMUNICATED TO AN OUTLET NOZZLE BY A CONDUIT HAVING A THROUGHBORE. THE CONDUIT TERMINATES IN AN OUTLET NOZZLE, AND PORTION OF THE CONDUIT DEFINES A DOSING CHAMBER FOR STORING A MEASURED DOSE OF THE LIQUID CALIBRANT. A THERMAL ACTIVATOR SUCH AS AS RESISTIVE COIL OR A RADIO FREQUENCY UNIT IS DISPOSED ADJACENT THE DOSING CHAMBER FOR APPLYING A STEEP THERMAL GRADIENT IN ORDER TO BRING THE CALIBRANT QUICKLY TO ITS BOILING SUCH THAT THE MEASURED QUANTITY IS EJECTED FROM THE OUTLET NOZZLE.
