The EC 3.0 Calibration Solution 100 ml bottle provides a reliable, NIST-traceable standard at 3000 µS\/cm (3.0 mS\/cm) at 25 °C to keep high-range readings accurate and trustworthy. This multi-use 100 ml size offers excellent value for frequent calibrations, with temperature-compensated values listed from 15–30 °C so you can adjust precisely for your grow-room conditions (e.g., 2943 µS\/cm at 24 °C). Close tightly after each use to maintain stability, and store between 15–25 °C away from sunlight — no contamination when handled properly. Ideal for weekly or bi-weekly checks on handheld pens, continuous monitors or automated controllers like the P160 Pro2, P700 Pro2 or C800 Pro when running concentrated bloom feeds. Sustainable, high-precision calibration that safeguards your crop investment and maximises bloom quality.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eNIST-traceable EC 3000 µS\/cm (3.0 mS\/cm) standard – lab-grade accuracy for high-EC ranges\u003c\/li\u003e\n\u003cli\u003e100 ml bottle size – economical for frequent use without waste\u003c\/li\u003e\n\u003cli\u003eTemperature compensation table – precise values from 15–30 °C for real grow-room accuracy\u003c\/li\u003e\n\u003cli\u003eMulti-use format – reseal tightly after each calibration to preserve integrity\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eStore 15–25 °C – stable \u0026amp; long-lasting when kept away from heat \u0026amp; direct light\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HydroGarden","offers":[{"title":"Default Title","offer_id":43843153035352,"sku":"AQU020","price":120.0,"currency_code":"ZAR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0681\/1510\/3832\/files\/ec-3-0-calibration-solution-4851-en-G.png?v=1773326400","url":"https:\/\/pot-tentialgrows.co.za\/products\/ec-3-0-calibration-solution-100-ml","provider":"Pot-tential Grows","version":"1.0","type":"link"}
