Battery Hydrometer Testing Electrolyte Level Density Lead Acid Specific Gravity

Had to return the first one as it had been smashed in transit, reordered and totally satisfied with the product

Does exactly what it says it does. Good quality and great value. Can't fault it on anything.

Item works well, as advertised. Simple to use just remember to pull the rubber ball to the end of the tube or it will not draw up sufficient fluid into the tube for an accurate reading. I would recommend this item, in all good value and a prompt delivery.

The uncertainty was lifted, I could instantly see which cells were mackerel on my battery.

It is only fair that I give the item 5 stars. Due to my own fault, I dropped the glass piece n cracked it whilst I was putting the pieces together

Problem was that a complete depression of the bulb failed to fill the tube sufficiently, so required two pumps. The fluid I was reading was intentionally weaker so the float sat higher in the tube, which may have exacerbated the problem.

Works perfectly found our damaged cell and confirmed the others were in good condition. You must move the bulb up to the correct position on the tube or it won’t suck enough into the tube to float the indicator.

Poor quality… the rubbers on the bowl and the end assembly is poor quality and bad fit Don’t waste your money

don't work poor quality

Produit conforme à mes attentes.

Ottimo prodotto. Unica nota, la parte in gomma dove si pesca l'acido sembra rifinita malissimo. In realtà è meglio lasciarla com'è per evitare che rotoli quando si appoggia sul tavolo

medidor de ácido de batería. Me guta que tenga las densidades y los colores en el lector. Fácil de usar. Buena calidad.

I make sure I rinse out after each use. So far good.
