Keep EC in your target range to help your achieve better results.\u003cbr\u003e\n\u003cbr\u003e\nDESIGN FEATURES\u003cbr\u003e\nMeasures conductivity and temperature with automatic temperature compensation.\u003cbr\u003e\nIdeal range for hydroponics (0.00 to 10.00 mS\/cm).\u003cbr\u003e\nUnits in mS\/cm easily convertable to ppm.\u003cbr\u003e\nFactory calibrated with the ability to recalibrate if needed.\u003cbr\u003e\nReplaceable electrode.\u003cbr\u003e\nFully waterproof to IP65.\u003cbr\u003e\n250 hours continuous use (3 x 1.5V batteries included).\u003cbr\u003e\n\u003cbr\u003e\n\u003cbr\u003e\nCARE AND USE\u003cbr\u003e\nMAINTENANCE\u003cbr\u003e\nEC electrodes can develop nutrient build up over time. To miminize build up, always rinse the probe in fresh tap water after every use.\u003cbr\u003e\n\u003cbr\u003e\nCONVERTING EC TO TDS\u003cbr\u003e\nThe Milwaukee EC Pen, like all conductivity meters, provides a measure of electrically charged ions in a solution and is an absolute measure of conductivity.\u003cbr\u003e\n\u003cbr\u003e\nEC 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.\u003cbr\u003e\n\u003cbr\u003e\nYour mS\/cm reading can be approximately converted to TDS (ppm) as shown in the examples below.\u003cbr\u003e\n\u003cbr\u003e\n2.00 mS\/cm = 2000 uS\/cm = 1000 ppm on .50 factor scale\u003cbr\u003e\n2.00 mS\/cm = 2000 uS\/cm = 1400 ppm on the 442 scale or .70 factor scale\u003c\/p\u003e\n","brand":"Alltronics LLC","offers":[{"title":"Default Title","offer_id":71398831554813,"sku":"EC66","price":45.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0844\/3258\/4957\/files\/aac4db85-0c43-5241-bcc7-2c91b0c5f2fb.jpg?v=1790550419","url":"https:\/\/1000watts.com\/products\/milwaukee-ec66-waterproof-high-range-conductivity-pen-with-atc","provider":"1000Watts","version":"1.0","type":"link"}
