## Overview

The RHA-505F ATC is a professional-grade 4-in-1 refractometer designed for automotive maintenance. It measures freezing points of antifreeze fluids (ethylene and propylene glycol), specific gravity of battery acid, windshield washer fluid concentration, and urea levels in diesel exhaust fluid (DEF). Featuring automatic temperature compensation for accurate readings in any environment, this durable glass instrument is favored by mechanics for reliable, multi-fluid diagnostics.

Review: Does its job! - this is one of those tools that you wont use that often, but when you need it well it definitely comes in handy. I bought because I am a mechanic and need to check the DEF in trucks for contamination. Its well built and will last forever as long as it is taken care of.
Review: Good Product - I was impressed at how easy it was to use, and much more accurate than the floating ball anti-freeze testers.

## Features

- The models have only one unit system: °F. With the indication we may know the freezing point of either ethylene glycol or propylene glycol based cooling systems. You can use this measurement tool to measure and Check Washer Fluid.With ATC(automatic temperature compensation) .
- Function 1: Measuring freezing point of automobile antifreeze based on ethylene glycol or propylene glycol(G11, G12, G13). Measuring Range: -60°F-32°F.
- Function 2: Measuring specific gravity of battery acid and provide a quick reference of battery charge condition. Measuring Range:1.10 to 1.40 kg/l
- Function 3: Measuring windshield washer fluid based on ethanol or isopropyl alcohol. Measuring Range: 32°F to -40°F
- Function 4:Measuring Urea Concentration in automobile diesel exhaust fluid (DEF). Measuring Range:30% to 35%
