Antifreeze Refractometer – Portable 3in1 Fahrenheit (°F) with Automatic Temperature Compensation (ATC) This professionalgrade portable antifreeze refractometer is designed for quick, precise measurement of automotive antifreeze systems, battery fluid condition, battery acid, glycol, and coolant. Built for ease of use and reliability, it provides vital information in seconds without the need for batteries, helping you maintain peak vehicle performance. Key Features and Benefits: • Accurate Freezing Point Measurement – Measures the freezing point temperature of ethylene glycol or propylene glycolbased automobile antifreeze coolant. Ethylene glycol range: 84°F to 32°F Propylene glycol range: 60°F to 32°F • Concentration Measurement – Determines concentration levels for both ethylene and propylene glycol coolants. Ethylene glycol range: 0% to 70% Propylene glycol range: 0% to 63% • Battery Acid Specific Gravity – Measures battery acid specific gravity to give a quick reference of battery charge condition. Range: 1.100 to 1.400 kg • Automatic Temperature Compensation – ATC function enables accurate readings regardless of changes in ambient temperature, eliminating the need for manual corrections. • Minimal Sample Requirement – Requires only 23 drops of liquid; results are available within seconds. • Battery Operation – No batteries needed, ensuring consistent performance without maintenance. Practical Applications: 1. Automotive Maintenance – Quickly check the condition of your vehicle's antifreeze and coolant to prevent engine damage in extreme temperatures. 2. Battery Servicing – Monitor battery acid levels to assess charge condition and ensure reliable starting power. 3. Fleet and Workshop Use – Ideal for mechanics, garage technicians, and fleet managers needing fast, reliable coolant and battery checks across multiple vehicles. Performance and Design: • Portable and lightweight for ease of handling in any workspace or field setting. • Durable construction suitable for frequent professional use. • Clear and easytoread scales simplify measurement interpretation. This 3in1 antifreeze refractometer combines accuracy, speed, and convenience in one compact tool, making it an essential instrument for anyone managing automotive cooling systems and battery maintenance.
