The lighted Refractometer

ZGR series has its own light source. With the built-in light source, it makes more convenient to use when in a Dark or Dim room or when doing wide-field work. And it also can use the outside light source to test. It is convenient to replace the batteries when they were use out.


The lighted antifreeze refractometer


Antifreeze refractometer are designed for testingfor concentration of the battery fluids, antifreeze liquid and cleaning fluids. With the indication of the percenage you may know at which temperature the fluid will be froze for both propylene glycol and ethylene glycol. It can also be used for checking the strength of electrolyte solution batteries.


ZGRA-300ATC models are equipped with °F unit system. With the indication of the temperature we may know the freezing point of either ethylene glycol or propylene glycol-based cooling systems.It can be used for checking the strength of electrolyte solution batteries. It‘s FULLY EQUIPPED with ATC that automatically adjust itself to correct temperature discrepancies during use. Refractive index is very temperature dependent, it is important to use a refractometer with automatic temperature compensation to give you the most accurate measurement in any type of environment temperature. Capable of measuring with high accuracy and provides precise results. It‘s equipped with vivid and sharp reticle chart for easy and comfortable reading. It uses ambient light only and no batteries are needed. Made by experienced craftsmen and are unlikely to break down! Get the RHA-300ATC for higher Antifreeze/Battery/Cleaning Fluid measuring needs.
