Hanna Marine Magnesium Checker HC HI783 Saltwater Aquariums, Marine, Aquaculture Applications Magnesium Tester 64 grams

Misst was er soll. Einfach in der Handhabung

Love being able to take 5 minutes out of my day to do the test. One tip, set a 30 second timer or the last step and shake vigorously. Then pop into the egg and hold the button till the 3 min counter starts. After 1 min is left open the egg and pull the glass vial out and tilt back n forth to dislodge any bubbles on the glass then pop it back in before the timer ends. That way you'll get a very very close reading if not a perfect reading. This is the new revision and works extremely well..

This one was a little more involved than the alk, PO4 and NO3 checkers but still easy enough to use and great to have a number instead of guessing on standard tests. Helps to gauge when to add more Mg to the system.

ahora si da los parametros correctos y se actualizo el firmeware con un contador de 3 minutos para determinar el valor de magnesio

Nice
