Automotive Coolant Refractometer with ATC

Precision Automotive Coolant Refractometer with ATC Technology

Ensure your vehicle's cooling system and battery are performing at their peak with this professional-grade Antifreeze Refractometer. Designed for accuracy and durability, this essential diagnostic tool allows mechanics and DIY enthusiasts to instantly measure the freezing point of glycol-based coolants and the charge level of battery acid.

Unlike traditional hydrometers that can be messy and inaccurate due to temperature fluctuations, this optical instrument features built-in Automatic Temperature Compensation (ATC). This technology automatically adjusts for ambient temperature shifts, ensuring you get a precise reading every time, regardless of the working environment.

Key Applications:

• Ethylene Glycol & Propylene Glycol: Accurately test the freezing point of standard automobile antifreeze/coolants to prevent engine damage in extreme cold.
• Battery Acid: Quickly assess the condition of lead-acid battery electrolyte solutions to determine charge status (1.15-1.30sg).

Product Features:

• High-Definition Optical Scale: Provides a sharp, direct reading line for instant analysis without guesswork.
• Ergonomic Design: Features a soft rubber eyepiece for comfortable viewing and a non-slip rubber grip for secure handling, even with gloved hands.
• Adjustable Focus: Manual focus ring allows you to calibrate the view to your eyesight for crystal-clear readings.
• Portable & Durable: Constructed with robust materials to withstand shop environments. Requires no batteries or power cords—it uses ambient light for operation.
• Complete Kit: Includes a protective soft carrying case, a bulb filler (pipette) for sample collection, a mini screwdriver for calibration, and a comprehensive instruction manual.
