• Practical Function: This dial-type coolant tester efficiently measures antifreeze concentration and coolant freezing point, making it useful in cold winters. It checks coolant condition to see if replacement is needed, helping protect the engine from extreme temperatures
• Clear Scale: The tester features a clearly marked temperature scale with both °F and °C readings, providing accurate measurements from -45℉ to 10℉ (-43℃ to -12℃). The well-organized layout allows quick, easy reading at a glance, making monitoring more straightforward and intuitive
• Durable Materials: The tester's bulb and hose are made from silicone for flexibility and elasticity, ensuring ease of use. The transparent body is crafted from sturdy PC material that resists breaking. Together, these materials ensure long-lasting performance under frequent use
• Ideal Size: The hose measures 5.3 inches in length with a diameter of 0.4 inches. The body size is 3.9 × 1.8 × 0.7 inches, with a silicone bulb diameter of 1.8 inches. These precise dimensions make the tester compact, easy to handle, and highly portable for on-the-go checks
• Easy to Use: Simply insert the hose into the coolant reservoir and draw coolant until it reaches the marked line on the tester body. As the fluid temperature changes, the dial pointer indicates the freezing point, allowing quick, hassle-free checks of coolant condition
