Brief Description
This refractometer (RHA-503ATC) is designed to test concentration of battery fluids, antifreeze liquid and cleaning fluids. Compared with other Battery Acid refractometers, this tool has 4 scales design to measure the freezing point of Windshield Cleaning Fluid. With the indication of the percentage of concentration, you will know at which temperature (°C) of the fluid will be frozen for Propylene Glycol, Ethylene Glycol and Cleaning Fluids.
Moreover, it can be used for checking the strength of electrolyte solution batteries in unit of Specific Gravity (sg). Specific gravity (sg) is the ratio of the density of a given solid or liquid to the density of water at a specific temperature and pressure.RHA-503ATC is built with Automatic Temperature Compensation (ATC), so that the refractometer is automatically adjusted to correct temperature discrepancies of environment temperature.
Features
- Quad-scale design to measure concentration or density of Battery Fluid, Propylene Glycol, Ethylene Glycol and Cleaning Fluids
- Sturdy and light weighted Aluminum body
- High quality and accurate testing result
- ATC Compensation Range (Built-in Automatic Temperature Compensation System) from 10°C to 30°C
- Easy and very convenient to use
- Can be easily calibrated with a mini-screw driver
What
does it do?
- It will tell you the freeze point of your ethylene or propylene glycol antifreeze!
?
- It will tell you the concentration of ethylene or propylene glycol antifreeze in water by percentage!
- It will tell you the condition of your battery by measuring the Battery Acids Specific Gravity - the weaker the acid SG, the weaker the battery strength!
