Product Description
Identify liquids and verify purity by refractive index with a portable instrument that needs no power. This handheld unit reads nD directly, giving chemists, quality technicians and educators a quick way to compare oils, solvents and other samples against reference values without moving them to a bench refractometer.
This listing is for catalog number 43055: Handheld Refractometer, NDX-2, 1.425 to 1.520 nD. A small drop on the optical glass prism is viewed through the eyepiece against ambient light, and the boundary line is read on a large, high-contrast refractive index scale from 1.425 to 1.520 nD. The prism sits in an all-metal housing for fast temperature equilibrium, and a rubber grip and non-roll stand improve handling. A case, pipette and manual are included. LIGHT LABS ships genuine Heathrow Scientific products with knowledgeable support from our Englewood, Colorado team.
