Review on 🔋 Unitec 74274 Battery Hydrometer: Accurate Hydro Volts Measurement for Efficient Battery Testing by Quinton Wonsley

I read that some people lost their electrolyte suction tube. The handset rises a full 1/2 inch - you really have to make an effort to toggle it on and off. The readings are very easy to read – the built-in compensation makes the whole process much easier. One trick I discovered right away is that you have to hold it properly in order for the wheels to stay balanced and swing freely. It takes a minute to get used to. It is much easier to use than a disc hydrometer or thermometer.
