{"product_id":"electroscope-dual-purpose-1","title":"Electroscope, Dual Purpose","description":"\u003cp\u003eA Dual Purpose Electroscope is a versatile physics instrument primarily used to detect the presence and nature of electric charges. It typically consists of a vertical metal rod housed in a protective case, featuring a metal plate or sphere at the top and thin, flexible leaves (often gold or aluminium) at the bottom.\u003c\/p\u003e\n\u003cp\u003eThe \"dual purpose\" designation generally refers to its ability to serve two core scientific functions:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eQualitative Detection: It serves as a sensitive detector to identify if an object is electrically charged and to determine the polarity (positive or negative) of that charge.\u003c\/li\u003e\n\u003cli\u003eQuantitative Measurement: Unlike basic models, it often includes a graduated scale that allows users to measure the specific angle of leaf deflection, providing a relative measure of the charge's strength or voltage.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSensitive Leaves:\u003c\/strong\u003e Uses thin gold or aluminium foil that diverges due to electrostatic repulsion when charged.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTransparent Scale:\u003c\/strong\u003e An internal scale allows for consistent, comparative readings of charge magnitude.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProtective Housing:\u003c\/strong\u003e Usually built with a metal or wooden case and glass windows to shield the delicate leaves from air currents and moisture.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEarthing Terminal:\u003c\/strong\u003e Many models include a 4mm socket for earthing, which is essential for experiments involving charging by induction or for neutralizing the device.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIonisation Chamber\u003c\/strong\u003e: The sliding glass panels allow for the insertion of ionising materials, enabling it to detect ionizing radiation.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eProduct of India\u003c\/p\u003e","brand":"SmartLabs","offers":[{"title":"Default Title","offer_id":46927135342745,"sku":"JN-PH0916B","price":207.0,"currency_code":"ZAR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0569\/3584\/1945\/files\/electroscope-dual-purpose-7394552.png?v=1777902436","url":"https:\/\/smartlabs.co.za\/products\/electroscope-dual-purpose-1","provider":"SmartLabs","version":"1.0","type":"link"}
