The meter operation is simplified with dedicated buttons for measurement modes to be displayed on the LCD and knobs for single point calibration of pH and EC\/TDS.\u003cbr\u003e\u003cbr\u003eThe HI9813-51 has a variable EC to TDS conversion factor that automatically changes from 0.56 to 0.78 ppm = 1 µS\/cm based on the actual EC reading. All readings are automatically temperature compensated using a temperature correction coefficient (ß) fixed at 2%\/oC. The HI9813-5 is suitable for agricultural, greenhouse and hydroponic applications.\u003cbr\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"font-family: Arial;\"\u003e- 3 in 1 probe with pH, EC\/TDS and temperature sensors\u003cbr\u003e- Amplified pH electrode for immunity to electrical noise including from ballasts and pumps\u003cbr\u003e- Large LCD with tutorial instructions\u003c\/span\u003e\u003c\/p\u003e","brand":"TOL Urban Cultivation Outlet","offers":[{"title":"Default Title","offer_id":47485223993593,"sku":null,"price":309.99,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0160\/4275\/4112\/files\/69105-B_042358ac-3c7b-437c-b499-fa5307212ccb.jpg?v=1772898466","url":"https:\/\/treeoflifeshop.ca\/products\/hanna-ph-ec-tds-temp-portable-meter-hi-9813-51","provider":"Tree of Life Inc.","version":"1.0","type":"link"}
