Beschreibung
Zusammenfassung:	The invention discloses a two-stage electroscope and aims at providing a two-stage electroscope capable of improving the operation safety. The two-stage electroscope comprises an operating rod, an electroscope head fixedly arranged on the operating rod, an electroscope contact and a conductor detection contact, wherein the electroscope contact is arranged on the electroscope head and is provided with a self-inspection button; a telescopic structure is adopted by the electroscope contact; the conductor detection contact is arranged on the electroscope head and is parallel to the electroscope head; the conductor detection contact is connected with the electroscope contact in parallel and is used for detecting whether an object in contact with the electroscope contact is a conductor or not; adisplay lamp used for displaying whether the object in contact with the electroscope contact is the conductor or not is arranged on the electroscope head; and the structure of the conductor detectioncontact is the same as th
