need it?<\/h3><div class=\"rank-math-answer\"><p>The EC20 measures electrical conductivity (EC), the total concentration of dissolved salts and therefore of your nutrients. In growing, EC is the most important control value next to pH: it tells you whether you are feeding too little or too much. It becomes especially powerful when you also measure your runoff, for example from a DrainMaster drip tray. If runoff EC climbs well above input EC, salts are building up in the substrate and it is time to flush.<\/p><\/div><\/div><div id=\"faq-question-dm2645-2el\" class=\"rank-math-list-item\"><h3 class=\"rank-math-question\">What is special about the BPB electrode?<\/h3><div class=\"rank-math-answer\"><p>BPB stands for brush-resistant platinum black, a robust platinum coating on the sensor. Conventional platinum electrodes lose accuracy once the delicate coating is touched or cleaned. The EC20&#8217;s BPB electrode tolerates cleaning and everyday use far better and holds its calibration longer. This is the main reason Apera EC meters stay more accurate than many cheap alternatives.<\/p><\/div><\/div><div id=\"faq-question-dm2645-3el\" class=\"rank-math-list-item\"><h3 class=\"rank-math-question\">How do I calibrate the EC20?<\/h3><div class=\"rank-math-answer\"><p>With a 1- or 2-point calibration and automatic buffer recognition: dip the electrode into the calibration solution (e.g. 1413 \u00b5S\/cm, included in the kit) and the meter recognises the target value itself. For growing, a single-point calibration at 1413 \u00b5S is completely sufficient. Calibrating once a month is usually enough, every two weeks under heavy use.<\/p><\/div><\/div><div id=\"faq-question-dm2645-4el\" class=\"rank-math-list-item\"><h3 class=\"rank-math-question\">How long does a set of batteries last?<\/h3><div class=\"rank-math-answer\"><p>Up to 1,000 hours on four AAA batteries, which are included. Auto power-off prevents a forgotten meter from draining them. Battery changes become something you practically never think about.<\/p><\/div><\/div><div id=\"faq-question-dm2645-5el\" class=\"rank-math-list-item\"><h3 class=\"rank-math-question\">EC, TDS, PPM: which one should I use?<\/h3><div class=\"rank-math-answer\"><p>They all describe the same thing: dissolved salts in water. EC is the direct physical quantity in mS\/cm or \u00b5S\/cm and the international standard. TDS (in ppm) is an estimate converted from EC, and different manufacturers use different conversion factors, which causes endless confusion. Our advice: work directly in EC and your numbers will match every feeding chart and every forum discussion. The EC20 displays EC directly.<\/p><\/div><\/div><\/div><\/div><p class=\"dm-vergleich-link\"><strong>Not sure which meter fits?<\/strong> \u2192 <a href=\"https:\/\/drain-master.de\/en\/apera-ph-ec-meter-comparison\/\">Read the full Apera comparison: PH20 vs PH60 vs EC20 vs EC60 vs PC60-Z<\/a><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"<p>The Apera Instruments EC20, an accurate and user-friendly conductivity meter, is the perfect choice for precise measurements of irrigation and drainage water.
