Review on π¬ High-precision AUTOUTLET Refractometer Saltwater Aquarium: Perfect for Seawater, Pool, Tank Testing, Marine Fishkeeping. 0-100PPT & 1.000-1.070 Salinity Tester with ATC Function, Hydrometer Specific Gravity Salinity Meter Kit β Buy Now! by Brendan Thorpe
Works perfectly.
Looks solid. Easy to use. I love that they include a small screwdriver to turn the calibration screw. I calibrated it and everything has been fine ever since. I can't tell you how many glass hydrometers I've broken. I keep one safe in the box now (only use it to confirm calibration from time to time). I'm only taking off a star because the case could be better. It works but seems like it will break or open if you drop it.
- Concentration measuring range
