4-in-1 Antifreeze Refractometer for Coolant, DEF, Battery Acid, and Washer Fluid
- 4 IN 1 FUNCTION: ❄Antifreeze refractometers measure freezing point of automobile antifreeze basied on ethylene glycol or propylene glycol, and measuring rang:-50 to 0 ℃. ❄Measure Urea Concentration in automobile diesel exhauset fluid (DEF) 30% to 35%. ❄Measure specific gravity of battery acid 1.10 to 1.40Kg/L. ❄Windshield washer fluid based on ethanol or isopropyl alcohol -40 to 0 ℃
- Better Accuracy& Reliable: ATC antifreeze coolant testers can compensate temperature automatically when ambient temp changes, excellent eliminate the deviation, and ensure the measured readings more precise
- Quick & Easy Using: Just 2 or 3 drops of solution, wait for few seconds and towards light, then get the accurate reading. The affordable coolant refractometer needs less sample solution than tradistional hydrometer and less expensive then digital refractometer but bettery accuracy
- Durable & Portable - Antifreeze tester is made of non-staining aluminum and ABS rubber, anti-rust, sturdy and resistand to abrasion for long perfermance. Comes with durable plastic box, lightweight, and easy for storage and carry with
- Practical Tool: The optics antifreeze refractometer is great tool to help you check freezing point of automobile antifreeze system, quick reference of battery charge condition, monitor DEF
