The water that is about to run through your coffee reveals how much mineral is dissolved in it. “Should be about right” becomes “this is it”.\u003c\/p\u003e\n\u003ch3\u003eWhat the device measures\u003c\/h3\u003e\n\u003cp\u003eWater is never just water, but a solution of H₂O and dissolved minerals such as magnesium, calcium and bicarbonate. Pure H₂O barely conducts electricity; the more minerals are dissolved in it, the more conductive it becomes. The Apax Lab TDS Meter measures exactly this conductivity and estimates the total dissolved solids from it – shown in PPM, parts per million.\u003c\/p\u003e\n\u003cp\u003eWhich individual minerals sit in the water is not something the device shows; it gives you the one number you can orient yourself by, day after day. And that counts: with too little mineral content, coffee often comes across as flat, because the water lacks the partners it needs to dissolve and carry aroma. With too much mineral content, the mineral impression settles over the finer notes. In between lies the range where body and clarity come together. Where exactly your optimum lies is also a matter of taste – there are no water laws and no water police, and our observation is one of many.\u003c\/p\u003e\n\u003ch3\u003eAt a glance\u003c\/h3\u003e\n\u003ctable class=\"ccc-compare-table\"\u003e\u003ctbody\u003e\n\u003ctr\u003e\u003ctd\u003eBrand\u003c\/td\u003e\u003ctd\u003eApax Lab, Australia\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eMeasuring principle\u003c\/td\u003e\u003ctd\u003eelectrical conductivity, estimated TDS derived from it\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eDisplay\u003c\/td\u003e\u003ctd\u003edigital readout in PPM, with HOLD button\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003ex10 symbol\u003c\/td\u003e\u003ctd\u003ewhen it flashes, multiply the displayed value by ten\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eMeasuring temperature\u003c\/td\u003e\u003ctd\u003earound 25 °C\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eImmersion depth\u003c\/td\u003e\u003ctd\u003e5 cm maximum\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eMeasuring time\u003c\/td\u003e\u003ctd\u003e10 to 30 seconds until the reading is stable\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eOperation\u003c\/td\u003e\u003ctd\u003eON\/OFF button, HOLD button, removable protective cap\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eNot suitable for\u003c\/td\u003e\u003ctd\u003ehot water\u003c\/td\u003e\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\n\u003ch3\u003eHow you go about it\u003c\/h3\u003e\n\u003cp\u003eCap off, press ON\/OFF – the display reads 000. Then hold the probe no deeper than five centimetres in water at around 25 degrees and let the value settle for 10 to 30 seconds. Once it holds still, the HOLD button keeps it on screen while you lift the device out of the water. Afterwards shake off the water or dab the probe dry with a clean tissue and put the protective cap back on. The device does not belong in hot water.\u003c\/p\u003e\n\u003cp\u003eIn everyday use that means: check your base water first – distilled or reverse-osmosis water sits close to zero. Then you mix your water to a recipe, measure, and know what you are brewing on. If the value is off, you adjust next time, and because the result is a number, it repeats exactly the next day. It is also how you check the mineral concentrates from our \u003ca href=\"\/en\/collections\/apax-lab\"\u003eApax Lab Collection\u003c\/a\u003e such as Tonik, Jamm, Lylac and Konflux.
