Description

The build-in automatic temperature compensation feature makes it get consistently accurate reading, no need to control the liquids temperature deliberately, just make sure it's at room temperature ( during 0-25 ℃) . Just need to take a few drops of your liquids on the prisms and hold the refractometer to the light, then look through the eyepiece, you can get the reading.

Features

- Color: As shown.
- Size: 19.50X4.00X4.00cm/7.66X1.57X1.57 inch.
- Material: Metal, rubber.
- Measuring range: 0-100%.
- The refractometer are based on the principle that the refractive indices of liquids change when the concentration change. 
- It's portable, easy, quick and no battery required, easier and more accurate than a traditional hydrometers, more affordable than a digital meter. 
- It's a perfect tool for adult or young, home or professional use.
- The internal optical lens with high refractive index make up the precision optical system.
- It has a simple design, but very practical in use, giving you a good using experience.
