{"product_id":"heating-furnace","title":"Heating Furnace","description":"Product Information: ..\u003cbr\u003eThe heating chamber can be employed to conduct the Franck-Hertz experiment or the sodium resonance fluorescence experiment in safety. It consists of a powder-coated sheet steel casing with two viewing windows. The front plate is attached via six knurled screws. The chamber is heated via a tubular heating element in the chamber floor. Temperature measurement and regulation is carried via an integrated micro-controller and a PT 100 thermocouple. A digital temperature display allows you to read off the temperature set-point and the actual temperature value. The “SET” button can be used to toggle the display between ° Celsius and ° Fahrenheit. The “+\/-” keys allow you to set the set-point for the temperature in steps of 1 K. There is an opening at the top with a spring clip for holding a thermometer and a thermally insulated carrying handle. The heating chamber can accommodate both the Franck-Hertz tube with Hg filling and the sodium fluorescence tube on furnace wall.","brand":"3B Scientific","offers":[{"title":"Default Title","offer_id":49419128865045,"sku":"3BS1012820","price":1947.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0857\/4897\/3845\/files\/U8482590-230_01_1200_1200_Heating-Furnace.jpg?v=1761028254","url":"https:\/\/unitedsupplycorp.com\/products\/heating-furnace","provider":"United Supply Corp.","version":"1.0","type":"link"}
