Battery Refractometer Temp Compensating

Battery Refractometer Temp Compensating

There is an easier way to measure your batteries specific gravity, without fussing with cheap gas station hydrometers, which never seem to be accurate anyhow. It's a device called a Refractometer.

The Refractometer is the most accurate conventional testing method available for determining specific gravity readings of electrolyte in lead acid batteries. Automatic temperature compensation provides immediate, accurate, direct readings without the need to measure temperature or apply a correction. This is the Refractometer we recommend.
