{"product_id":"hm-digital-tds-ez-water-quality-tds-tester","title":"HM Digital TDS-EZ Water Quality TDS Tester","description":"A TDS meter (aka ppm pen, nutrient tester, tds stick) is an inexpensive and convenient digital tool to instantly check your overall water quality. TDS = Total Dissolved Solids, which is any salt, metal or mineral in the water. With the push of a button, the TDS-EZ can tell you your overall water purity level, which will be displayed on the screen in ppm (parts per million).\u003cbr data-mce-fragment=\"1\"\u003e\u003cbr data-mce-fragment=\"1\"\u003eThe lower the TDS level, the purer the water, with 0 ppm being pure H2O. The TDS-EZ is great for checking your tap water quality, or knowing when to change a filter. (The meter does not test for biological contaminants.) The TDS-EZ is a great tool for drinking water, water filtration and purification, hydroponics (test your nutrients), aquariums, RO\/DI systems, pools and spas, and more.\u003cbr\u003e\n\u003cul\u003e\u003c\/ul\u003e","brand":"HM Digital","offers":[{"title":"Default Title","offer_id":44259203809520,"sku":null,"price":29.99,"currency_code":"CAD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0609\/7482\/5712\/files\/Capture_74145f9c-4d01-4fa9-a9db-1b89f30e51af.jpg?v=1696354963","url":"https:\/\/www.saltwaterprosreef.ca\/products\/hm-digital-tds-ez-water-quality-tds-tester","provider":"Saltwater Pros Inc.","version":"1.0","type":"link"}
