Digital Coolant Refractometer


VEE GEE Scientific's MDX-603 Digital Coolant Refractometer measures the concentration and freezing point of the coolants ethylene glycol and propylene glycol.

Our coolant refractometer delivers quick, digital accuracy with high-end performance features like automatic temperature compensation (ATC) and continuous loop average readings. It also features IP65/67 ratings making it ideal for use in the field and in a multitude of environments.

This coolant refractometer has easy operation with a large digital LCD display that shows all of the needed data on screen. This digital refractometer also yields quick results, simply place 4-5 drops of your sample into the well, close the prism cover, and press the "READ" button... it's that simple!

The 4 scales included in this digital coolant refractometer (ethylene glycol, ethylene glycol freezing point, propylene glycol, and propylene glycol freezing point) can be used in a wide variety of applications including light industrial, chemical, and automotive.
