Hand Refractometer for Battery and Antifreeze, ATC, Built-in LED Illuminator

Hand Refractometer for Battery and Antifreeze

is a handheld refractometer used to determine the specific gravity (sg) of electrolyte solution batteries as well as the freezing point of propylene or ethylene glycol-based coolants in degrees Celsius (°C). Maintaining the proper antifreeze concentration in an engine can prevent costly repairs. Thus, this tool is used worldwide by trucking and automotive technicians to ensure proper dilution. This refractometer works well for measuring cleaning products too. The instrument also gives indication of the charge level in battery acid.

The ultra-smooth focusing eyepiece provides high-quality optics, presenting an easy-to-read scale on a semi-transparent blue background. Ambient room lighting offers ample illumination to clearly read the results.

USE OF A REFRACTOR
Using the instrument is simple. First the surfaces of the prism and the cover are washed with distilled water and carefully wiped (This cleaning is done after each use of the instrument).

Calibration

Before the measurement is made, the instrument is adjusted by placing 1-2 drops of distilled water at a temperature of 20 ° C, on the surface of the prism covered with the movable cover. Looking at the field of view in the light, the line separating the light from the dark field must coincide with the 0 of the scale, if it does not coincide then turning the adjusting screw is arranged to coincide.

Measurement

After adjusting the instrument, 1-2 drops of the liquid are placed on the surface of the prism and the field of view in the light is observed. The reading occurs when by moving the instrument screw, the dividing line separating the light from the dark field is clearly displayed.
