3 in 1 Scale Clinical Refractometer with 10~30°C ATC, Serum Protein 0~12g/dl, Urine Specific Gravity 1.000~1.050, Refractive Index 1.333~1.360 RI for Human Use.

Perfect for my students learning how to use the refractometer.

Works just great for what need. Lightweight quality is ok. Very easy to use. Nice product foe the money

This seems to be a professional grade product. I have a cat who has kidney problems and I can track how she's doing by checking her urine specific gravity, but it costs me $75 each time I take her to the vet for a urinalysis. Based on that cost, and that I've used this product twice with really helpful results, it is a bargain and I couldn't be more pleased with my purchase. It comes in an attractive storage case with a special cleaning cloth for the refractive surface.

Stay away don't order ... complete junk doesn't even focus right out of the box.

The refractometer itself worked just as it should and arrived quickly. My only complaint is the case that it comes with the latch is broken so the case does not stay locked closed. Not a major problem but definitely an inconvenience when taking the refractometer anywhere.
