Good idea, just make sure you keep it calibrated, they seem to go out of whack, quicker than a Refracto or TDS meter.I struggled with a Hydrometer for a month. Not that accurate. Bought a Refractometer today. Mixing and testing water is a breeze and very accurate. I suggest you get one, its never a a waste. Next thing on my list will be a PH Pen once the test kit is finish.
I paid about R480-00
Yeah basically thats what i do (part of my caliberation theory) only when i find it off then i adjust it.I know you guys say a refractrometer needs calibrating quite often, but I have done it once and never again, ok test it with ro water but have never needed to calibrate it again. You must clean it with RO water after use, or it may give a false reading.
When i look back its funny, but at the time i nearly had a stress induced stroke. I frequently take my refractometer to work. One day while unloading my bakkie it accidently fell. I opened the case (which is padded with foam) and inspected. No problem; and gave it no further thought. The following Sunday morning; while waiting for my first cup of expresso to brew; i decided to take a SG reading. Now picture this...Mornings for me especially Sunday mornings after Super 14 are slow. Very slow. Like a bear waking after hibbernation. I squeezed the drop onto the lense and then peered through the peeper looking for a source of light. My tongue and finger tips went numb, my lips dry, my chest had its first speed wobble, my temples and my eye sockets flushed with blood. Time stopped. Briefly.... I had a reading of that just above fresh water. The adrenaline slammed into my semi concious brain accelerating it from 0 - 100 in a flash. I clumsily took another reading and ....got the same result. I then carefully wiped the lense and gave the pippette a good squishing making a mental note to focus and not to panick.. Took another reading... the same. Frikkin Flying Battleships.. The lights had'nt come on yet but i could have sworn that my fish were looking green around the gills.I know you guys say a refractrometer needs calibrating quite often, but I have done it once and never again, ok test it with ro water but have never needed to calibrate it again.
