AB ToolsBattery Hydrometer Testing Electrolyte Level Density Lead Acid Specific Gravity

Just what i was looking for, great product.

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.

Nozzle end will not stay on when bulb is pressed - I was using it, the nozzle came off and battery acid sprayed all over the workbench - this product is dangerous and could cause an accident, I have thrown it in the bin and will order a different product from another supplier!

Good price. Haven’t used it yet,
