The mould quality is not up to the mark and price of the product. However it serves the purpose.

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.

works well, compact size, good quality, accurate compared with bulb type hydrometer. Plastic construction won't break in the tool bag.

Worked well for monitoring/bringing back 6v batteries on my lift. Batteries were charging for 3days while I monitored the PH with this tool and was able to see it increasing daily vs assuming if batteries were improving. Let's you know if they'll hold a charge or if you're wasting your time charging. Use only "distilled" water if refurbishing/filling
