Keep EC in your target range to help your achieve better results.\r\u003cbr\u003e\r\u003cbr\u003eTEMPERATURE COMPENSATION: Automatic\r\u003cbr\u003eACCURACY: EC: �2% Full Scale\r\u003cbr\u003eRANGE: 0 to 20,000 �S\/cm\r\u003cbr\u003e\r\u003cbr\u003e� Measures conductivity and temperature with automatic temperature compensation\r\u003cbr\u003e� Ideal range for hydroponics (0 to 20,000 �S\/cm)\r\u003cbr\u003e� Units in �S\/cm easily convertable to ppm\r\u003cbr\u003e� Factory calibrated with the ability to recalibrate if needed\r\u003cbr\u003e� 350 hours continuous use (3 x 1.5V batteries included)\r\u003cbr\u003e\r\u003cbr\u003eEC electrodes can develop nutrient build up over time. To miminize build up, always rinse the probe in fresh tap water after every use.\r\u003cbr\u003e\r\u003cbr\u003eThe Milwaukee EC Pen, like all conductivity meters, provides a measure of electrically charged ions in a solution and is an absolute measure of conductivity.\r\u003cbr\u003eEC is often converted to TDS in parts per million (ppm). Different scales include the 500 scale, 650 scale and the 700 scale. However, true PPM can only be determined through chemical analysis.\r\u003cbr\u003eYour mS\/cm reading can be approximately converted to TDS (ppm) as shown in the examples below.\r\u003cbr\u003e2,000 �S\/cm = 2.0 mS\/cm = 1000 ppm on .50 factor scale\r\u003cbr\u003e2,000 �S\/cm = 2.0 mS\/cm = 1400 ppm on the 442 scale or .70 factor scale\u003c\/p\u003e","brand":"IDROGROW","offers":[{"title":"Default Title","offer_id":53420813844812,"sku":"1076","price":38.66,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0698\/1045\/4801\/files\/84363_2.jpg?v=1758532905","url":"https:\/\/growtonia.com\/fr\/products\/milwaukee-cd611-ec-tester-digital-pen-1","provider":"Growtonia","version":"1.0","type":"link"}
