Digital Coolant Refractometer Freezing Point Refractometer For Ethylene Glycol

Description

Digital Coolant Refractometer Freezing Point Refractometer For Ethylene Glycol
Overview
A refractometer is an instrument to measure the concentration of aqueous solution by measuring it’s refractive index. All water based solution can make light bend.thebending of light increases at a rate proportional to the increasing solution concentration. Digital refractometer is a precise optical instrument.it’s characterized by small volume,light weight,graceful in shape and easy to operate.there fore it can be used by all sides.
Features
This model can be used for measuring the freezing point of either ethylene glycol or propylene based cooling systems and cleaner.it can be used for checking the strength of electrolyte solution batteries.
