No mercury.\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe length is the reason to buy this one rather than the 205mm. At 300mm the scale stays out of a tall beaker, above a bunsen, or clear of the rim of a deep container - so a student can read it without lifting it out and losing the temperature they were measuring.\u003c\/p\u003e\u003cp\u003eRed spirit rather than mercury: readable from a distance, and nothing hazardous if the tube breaks. One degree increments are the right resolution for school work - fine enough to plot a cooling curve, coarse enough to read quickly.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow to read an immersion depth.\u003c\/strong\u003e A partial-immersion thermometer is calibrated to be accurate when the liquid comes up to a marked depth on the stem - 76mm here - not when the whole thing is under. Push it further in or leave it shorter and the reading drifts. It is the single most common reason a class gets three different answers off three identical thermometers.\u003c\/p\u003e\u003cp\u003eMade in the UK. On a measuring instrument that matters, because accuracy is the entire product.\u003c\/p\u003e","brand":"MTA Essentials","offers":[{"title":"Default Title","offer_id":53792748929387,"sku":"EVSER1028003","price":10.2,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0963\/2795\/8891\/files\/ser1028003_thermometer-8211-spirit-red-8211-partial-immersion.webp?v=1788352550","url":"https:\/\/megaofficesupplies.com.au\/products\/lab-thermometer-300mm-10-to-110c","provider":"Mega Office Supplies","version":"1.0","type":"link"}
