It provides a salinity range of 0–100‰ (ppt) and a specific-gravity range of 1.000–1.070, making it particularly useful for aquariums, aquaculture, fish hatcheries, marine research and environmental water-quality monitoring. The STX-3 uses a high-quality optical glass prism and a large, high-contrast analogue scale for quick readings. Its automatic temperature compensation (ATC) operates from 10 to 30°C, with readings compensated to 20°C. The rugged metal housing and rubber grip are designed for reliable field use, while the non-roll stand helps keep the instrument stable when placed on a flat surface. \u003cspan class=\"contents\"\u003e\u003cspan class=\"\"\u003e\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eVEE GEE Scientific STX-3\u003cspan class=\"PDq2pG_selectionAnchor\"\u003e\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e0–100‰ (ppt) salinity range\u003c\/li\u003e\n\u003cli\u003e1.000–1.070 specific-gravity range\u003c\/li\u003e\n\u003cli\u003eAutomatic temperature compensation\u003c\/li\u003e\n\u003cli\u003eATC range of 10–30°C\u003c\/li\u003e\n\u003cli\u003eHigh-quality optical glass prism\u003c\/li\u003e\n\u003cli\u003eLarge, easy-to-read scale\u003c\/li\u003e\n\u003cli\u003eHigh-contrast display\u003c\/li\u003e\n\u003cli\u003eDurable all-metal construction\u003c\/li\u003e\n\u003cli\u003eNon-slip rubber grip\u003c\/li\u003e\n\u003cli\u003eNon-roll stand\u003c\/li\u003e\n\u003cli\u003eTool-free zero calibration\u003c\/li\u003e\n\u003cli\u003eCompact and portable\u003c\/li\u003e\n\u003cli\u003eSuitable for field, laboratory and aquaculture use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/dynamicaquasupply.com\/products\/refractometer-replacement-cover-plate-assembly-vee-gee-brand\"\u003e\u003cspan style=\"color: #0000ff;\"\u003eReplacement Cover Plate Assembly\u003c\/span\u003e\u003c\/a\u003e\u003c\/p\u003e","brand":"Vee Gee","offers":[{"title":"Default Title","offer_id":7683323887659,"sku":"43036","price":148.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2593\/8322\/products\/43036.jpg?v=1514487911","url":"https:\/\/dynamicaquasupply.com\/en-us\/products\/vee-gee-43036-stx-3-handheld-salinity-refractometer","provider":"Dynamic  Aqua-Supply","version":"1.0","type":"link"}
