Engine Coolant/Antifreeze and Battery Tester

Product catalog summary

Introduction
The Rhino Duo-Chek Engine Coolant and Battery Test Refractometer is a reliable tool for testing engine coolant freeze points, glycol concentration, and battery charge conditions. It features automatic temperature compensation for accurate readings of ethylene glycol, propylene glycol, and battery electrolyte.

Specifications

Measures freeze point and concentration of ethylene and propylene glycol coolants.
Determines battery electrolyte specific gravity and charge level.
Water-resistant, dustproof, and shock-resistant design.
Automatic temperature compensation for accurate measurements.
No batteries required, ensuring reliability.
Durable black polycarbonate housing.
Six measurement scales included.
Meets ASTM standards for confidence in measurements.

Models and Measurement Ranges

Model DC 70 and DC 60 with specific gravity range of 1.100-1.400.
Antifreeze protection for ethylene glycol from +32° to -60°F and propylene glycol from +32° to -60°F.
Coolant concentration scale for ethylene glycol 0-70% and propylene glycol 0-63%.
Refractive index range of 1.3330-1.4048.
Calibration with distilled water.

Importance of Testing Engine Coolant
Proper coolant concentration prevents engine block freezing and overheating. Under or over-concentration can cause cavitation, corrosion, and system plugging. Testing ensures maximum effectiveness and prevents serious engine damage.

Accuracy and Standards
The Rhino Duo-Chek meets ASTM D3321-94 (2002) standards, ensuring accurate measurements within ±1°F. A survey showed mechanics prefer testers with ±5°F accuracy. Tests revealed hydrometers can be inaccurate by up to 23°F, while the Duo-Chek was off by only 1°F.

Conclusion
The Rhino Duo-Chek refractometer is a superior choice for accurate and reliable engine coolant and battery testing, offering significant advantages over traditional hydrometers.

Engine Coolant/Antifreeze and Battery Tester-2

Why test engine coolant? Is there an Official Test Method or Standard for testing engine coolant? Everyone knows that the proper concentration of engine coolant will keep the engine block from freezing and cracking in the winter months. On the other hand, the engine coolant will keep the engine from boiling over in the summer months. But did you also know that: Yes, ASTM D3321-94 (2002) ֓Standard Test Method for Use of the Refractometer for Field Test Determination of the Freezing Point of Aqueous Engine Coolants This test method calls for accurate measurements not to vary more than 1 deg F (0.5...
