Salinity Refractometer with Automatic Compensation

Check a small saltwater sample without an electronic meter. This optical refractometer shows salinity and specific gravity on a dual scale for suitable aquarium and mixing routines.

✅ Read two references from one sample - The dual scale puts salinity and specific gravity together through the eyepiece.

✅ Use only a few drops - The prism takes a small sample rather than a filled measuring container.

✅ Keep it ready without charging - The optical design needs no battery or charging cable between uses.

Give the Mix a Recorded Reference

When preparing saltwater, sample consistently and compare the reading with the requirements of your system. Record the result alongside the mixture so a later adjustment has a useful reference.

Calibrate with an appropriate standard and follow the temperature and cleaning instructions. Clean the prism between samples and use a consistent method when comparing batches, so each recorded reading has the same practical reference.
