I recently purchased two Hydro Volts hydrometers and one ATC 4-in 1 refractometer to measure battery acid specific gravity in order to adjust battery charging parameters. I suspected that all these instruments were quite a bit inaccurate because they all gave different results. It turns out most hydrometers and refractometers give results with errors that are way too large especially when charging large expensive batteries. One Hydro Volts hydrometer gives results that are .017 lower than expected. Another Hydro Volts hydrometer gives me results that are .003 higher than expected. The 4-in ATC refractometer gives me results that are .010 higher than expected. To identify the accuracy error, I compared the results with a very high precision weight scale. I measured the actual specific gravity of the acid using a high pre cision weight scale. You measure the weight of a known volume of distilled water and compare it with the weight of the same volume of acid. The weight of the acid divided by the weight of the same volume of distilled water gives you a very precise value of the actual specific gravity. All the hydrometers and refractometers can be used but should be corrected for their specific errors. I think it is especially important to do so when charging large expensive batteries. I encourage everyone to make the same tests and make sure they test the accuracy of their hydrometers and refractometers. Charging batteries incorrectly causes battery damage and premature failure. For large and expensive lead acid batteries, It is very important to charge them very accurately by measuring the specific gravity very accurately.

Erstmal das Teil kam ordentlich verpackt an,und wurde auch fix geliefert.Prompt das Teil ausgepackt,und ausprobiert,zeigt die selben Werte an,wie mein Hella Hydrovolt,also wird's wohl passen. Macht was es soll,was will man mehr.

Kam zwar schneller an, als erwartet. Da es aber absolut nicht das ist, was bestellt wurde, geht es postwendend zurück. Geht gar nicht, sowas. 🤬

I think these are made in Germany, but not sure. Ten years ago, I bought one marked with the Hella brand name. It was blue. This one is identical but red and marked with Midnite. I guess the maker sells these to various retail companies for promotional purposes. Right now Midnite has the franchise. It is a very good and precise device. The black squeeze bulb lasted ten years with testing 60 battery cells every 60 days before it developed a small air leak and would no longer draw enough acid into the test chamber to make accurate readings - so that probably somewhat over 10,000 bulb-squeezes. I will buy another one in ten years.

Nachdem ich ihn das erste Mal benutzte, wollte ich schon eine schlechtere Bewertung schreiben. Habe auch den ersten Versuch die Anzeige für die Skala nicht entdecken können. Dann schon.Man kann (soweit die Batterie es erlaubt) wunderbar den Säuregehalt messen und entsprechend "einstellen".Funktioniert top. Auch der Saugschlauch ist meines Erachtens lang genug.

I can't figure out why this style hydrometer has not completely replaced the glass tube type hydrometers. Temp compensated automatically, easy to read, no glass float to stick to side of glass tube which can cause reading errors, accuracy appears to match that of a quality glass tube type hydrometer when it is done correctly, well made. It is expensive, and the glass tube types are so cheap, but this is truly a joy to use. I trust the reading from this over the glass tube style hydrometers.
