RHA-503ATC models are equipped with °C unit system. With the indication of the percentage we may know the freezing point of either
ethylene glycol or propylene glycol-based cooling systems. And they can also be used to test the concentration of ethylene glycol
or propylene glycol in antifreeze liquids. There's also an additional scale for measuring the freezing point of windshield
cleaning fluid. 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-503ATC and be able to
measure four main types of Antifreeze/Battery/Cleaning Fluids! Measurement
E:-50°C-0°C
P:-50°C-0°C
C:-40°C-0°C
B:1.100-1.400sg The liquid measurement is very easy. Place a few drops of the liquid on the optical part of the refractometer, cover the prism (the liquid will spread more easily over the prism), look throught the eyepiece against the light (focus, if necessary) and you will be able to read the result value on the scale.
