Lightweight and Portable Refractometer with LED Lighting

We are using the PCE-032-LED model refractometer in our laboratory for research work. We are using this instrument to determine the refraction properties of different liquids like emulsions, cooling lubricants, glues, and many more. We are using this instrument especially for low or artificially lit environments because it is perfectly suitable. In my opinion the optic of this instrument is not strong enough to absorb shocks and impact, because our instrument's optic was broken with a collision between the optic and a small stone on the site. It cost some money to repair it but now it's working completely fine. The accuracy of this instrument is very good and it is ± 0.2%. It is very lightweight and portable so we can use it anywhere we want. I recommend this instrument definitely for determining refraction properties.
