Review on 🔬 Highly Accurate Veterinary Refractometer 1,000-1,050 Refractive Index 1.333-1.360 (RI) by Jeff Leu

I am very pleased with how this device is 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 giving 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.
