Test battery acid safer and more accurately. The MISCO digital refractometer is ideal for testing the sulfuric acid concentration, or specific gravity, in lead-acid batteries and backup power systems. Old traditional analog refractometers force you to bring dangerous battery acid up to your face and eyes to take a reading. This risk is virtually eliminated with the MISCO digital refractometer, which is much safer and easier to use.
Measurement of sulfuric acid specific gravity is fast and easy with the MISCO digital refractometer. You need only a drop or two of battery acid for an accurate test. The refractometer is quick, convenient, and simple.
