A leak test apparatus includes a housing having an interior sized for retaining a plurality of instrument components including a control unit. A sniffer gun is linked to the instrument components, the sniffer gun having an intake point, and a test leak includes a gas reservoir, a constriction, an opening suited for introducing the intake point of said sniffer gun, and a temperature sensor. The temperature sensor is linked, either by means of a wired connection or wirelessly to the control unit for signal transfer.

We claim: 1. A leak test apparatus comprising: a housing having an interior sized for retaining a plurality of instrument components, said instrument components including a control unit; a sniffer gun linked to said instrument components, said sniffer gun having an intake point; and a test leak including a gas reservoir, a constriction, an opening suited for introducing the intake point of said sniffer gun, and a temperature sensor, said temperature sensor being linked to the control unit for signal transfer. 2. A leak test apparatus as recited in claim 1, wherein said test leak further includes an EEPROM, said EEPROM having at least one of production date, filling quantity and leak rate data stored within. 3. A leak test apparatus as recited in claim 1, wherein the constriction is a diaphragm. 4. A leak test apparatus as recited in claim 2, wherein the EEPROM is linked to the control unit for signal transfer. 5. A leak test apparatus as recited in claim 4, wherein the link between said EEPROM and said control unit is wireless. 6. A leak test apparatus as recited in claim 2, wherein said test leak is further equipped with a processor and data storage means, said EEPROM being linked to said processor and said data storage means. 7. A leak test apparatus as recited in claim 1, wherein the gas reservoir is located in a pressure vessel and an outer housing is provided for receiving said pressure vessel, wherein said outer housing includes said constriction as a component thereof. 8. A leak test apparatus as recited in claim 7, wherein the pressure vessel and outer housing are cylindrically shaped, said constriction being located in a face side of said housing and in which the face side opposite said face side having the constriction is equipped with a releasable screw cap. 9. A leak test apparatus as recited in claim 8, in which the outer housing includes a flange in the face side opposite said releasable cap, said flange projecting inwardly toward the interior of said housing for supporting the pressure vessel containing said gas reservoir. 10. A leak test apparatus as recited in claim 8, wherein the pressure vessel includes a ball valve disposed in the area of the releasable cap, said releasable cap carrying a pin which opens said ball valve when the cap is screwed in place. 11. A leak test apparatus as recited in claim 8, wherein said releasable cap carries a spike, said spike being oriented to penetrate said pressure vessel when the cap is screwed in place. 12. A leak test apparatus as recited in claim 8, wherein said releasable cap includes a rim having a bore defined in an upper side thereof. 13. A leak test apparatus as recited in claim 9, wherein the constriction is a diaphragm. 14. A leak test apparatus as recited in claim 13, wherein the flange carries said diaphragm. 15. A leak test apparatus as recited in claim 7, in which said outer housing is equipped in the area of said constriction with a pipe connection and in which the unoccupied end of said pipe connection forms said opening suited for introducing the intake point of said sniffer gun. 16. A leak test apparatus as recited in claim 1, wherein the leak test apparatus housing includes a port which is sized to permit said test leak to be selectively insertable into and removable from said apparatus housing through said port.
