{"product_id":"gras-40saprobe-microphone","title":"GRAS 40SA Probe Microphone","description":"The GRAS 40SA is constructed with detachable stainless-steel probe tubes which guide the acoustic signal to a microphone inside the housing of the 40SA. After being sensed by the microphone, the acoustic signal is passed on to an impedance matching wave guide which eliminates unwanted internal reflections. The result is a smooth frequency-response ranging from 2 Hz up to 20 kHz.","brand":"GRAS","offers":[{"title":"Default Title","offer_id":48310105538893,"sku":"40SA","price":0.0,"currency_code":"SEK","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0755\/9344\/9805\/files\/40SA_HiRes-RGB.png?v=1701172364","url":"https:\/\/gomeasure.dk\/en-se\/products\/gras-40saprobe-microphone","provider":"GOmeasure.dk","version":"1.0","type":"link"}
