4 in 1 Hand Held Car Refractometer What it tests Antifreeze Battery fluid Urea solutions (DEF) Key benefits Versatile 4 in 1 measurement: Run antifreeze, battery fluid, and urea testing with one handheld device, enabling you to assess freezing points and coolant concentrations quickly. Accurate concentration testing: Provides precise measurements for automotive urea solutions, helping keep vehicle urea concentration within the 3035% range. Easy handheld operation: Compact, handheld design for rapid detection of automotive fluids. Size is 27 x 40 x 160 mm, making it practical for car manufacturers, fleets, and service providers. Automatic temperature compensation: ATC from 0 to 30 °C ensures accurate readings across varying environmental conditions. Product attributes Function: Measures freezing point and coolant concentration for antifreeze, battery fluid, and urea solutions Compatibility: Designed for automotive fluids including antifreeze, battery fluid, and urea solutions Size: 27 x 40 x 160 mm Material/Construction: Handheld, compact design suitable for onsite use Performance: Automatic temperature compensation (0–30 °C) for consistent results Use scenarios Auto service : Quickly verify antifreeze quality and coolant concentration during routine maintenance to prevent overheating or freezing issues. Fleet maintenance: Regularly check DEF (urea) concentration to ensure proper exhaust aftertreatment and vehicle performance (target 30–35%). Field testing / manufacturing line: Onsite fluid verification for quality control and quick decisionmaking during production or largescale vehicle testing. Why this stands out Allinone measurement saves time and eliminates the need for multiple devices Clear, reliable readings with automatic temperature compensation Compact, portable design suited for workshops, fleets, and onsite testing while maintaining accuracy and ease of use
