Initially I concluded it was not consistent BUT now
I initially wrote this: 'Easy to use but the results are not consistent. If I take three readings from the same cell they will all be different.' BUT MY ENGINEER TELLS ME THAT IF YOU TAKE MULTIPLE READINGS QUICKLY FROM THE SAME CELL YOU GET DIFFERENT RESULTS. SO MAYBE IT IS OKAY.

Easy to read.
Bought to replace my normal hydrometer. Easy to read and easy to use and of course made in the USA.

Gehäuse undicht
An sich ein gutes Produkt. Es ist gut ablesbar, für meine Zwecke musste ich den Schlauch abändern. Das Gehäuse war jedoch an der Klebung der Gehäusehälften undicht. Das bedeutet, es zieht beim Einsaugen der Säure Luft. Eventuell durch den Transport verursacht, da nur in einer Papiertüte verschickt. Ich hätte das am liebsten reklamiert, aber durch die lange Lieferzeit habe ich mir die Mühe gespart und stattdessen das Gehäuse geklebt. Funktioniert jetzt wie es soll. Entweder besser verarbeiten oder besser verpacken wäre sinnvoll.

Great price great quality product!
Does EXACTLY what it’s supposed to do! As forklift mechanic we’re contacting acid levels in our electric forklift batteries and this gets the job done quick and efficiently!
