{"product_id":"radiometer","title":"Radiometer","description":"\u003cp\u003eThese curious and mesmerising instruments measure the power of electromagnetic radiation. Made from a glass bulb with much of the air removed to form a partial vacuum, inside is a set of fine metal vanes, each with one dark and one light side, mounted on a spindle. The vanes rotate, as if by magic, when exposed to sunlight, artificial light, or infrared radiation (even the heat of a hand nearby can be enough) – the more intense the light, the faster the rotation.\u003c\/p\u003e","brand":"Nauticalia","offers":[{"title":"Blue Base \/ 6.5\"","offer_id":42540504088745,"sku":"7685","price":27.49,"currency_code":"GBP","in_stock":false},{"title":"Blue Base \/ 8\"","offer_id":42540504121513,"sku":"7688","price":27.49,"currency_code":"GBP","in_stock":false},{"title":"Clear Base \/ 6.5\"","offer_id":42540504154281,"sku":"7689","price":21.99,"currency_code":"GBP","in_stock":false},{"title":"Clear Base \/ 8\"","offer_id":42540504187049,"sku":"7687","price":14.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0621\/4523\/3065\/products\/7685_42178c37-4484-4b4b-b442-b107adda4cdc.jpg?v=1663832922","url":"https:\/\/nauticalia.pro\/products\/radiometer","provider":"Nauticalia","version":"1.0","type":"link"}
