Review on 🔬 Clinical Refractometer with Tri-Scale Serum Function - 1,000-1,060SG Veterinary by Nick Brunner

I am very pleased with how this tool was built for only about $20 complete with nice box and accessories! You can't buy a lot of good stuff for $20 these days. It's easy to work with, just make sure you're using the right scale on the screen! If like me you need urine specific gravity make sure you use this scale and no others! Make sure to calibrate it to "0" with this scale! As for the doctor here who gave it a bad grade for confusing it with the scale, I say hey think and research what a scale needs before judging the instrument. It's not exactly rocket science as to which scale to use based on your needs. After all, it is a versatile tool.
