Practical Function: Designed to quickly measure the freezing and boiling points of coolant, this antifreeze tester effectively prevents engine failures caused by freezing in the winter and overheating in the summer. The transparent reservoir makes it easy to check antifreeze color and contaminants, ensuring optimal engine performance in all seasons

Accurate Readings: Equipped with a high-precision sensor, this coolant tester is double calibrated in °C and °F, with a clear scale and precise pointer to provide accurate readings quickly. The wide reading range of -45°F (-43°C) to 268°F (131°C) makes it easy for users to monitor the condition of the coolant and ensure that the system is operating properly

Easy Operation: To use it, simply insert the hose into the coolant reservoir, draw the fluid to the marking line, align the purple float with the centerline, and read the freezing point with the pointer for quick measurements. Compact in design, this coolant test strip is easy to access and use anytime to monitor your coolant status

Durable Construction: Made of high-quality PC material, this antifreeze coolant tester measuring device is sturdy and durable, offering excellent insulation, heat resistance and strong impact resistance. The flexible silicone hose ensures stability and reliability during frequent use, providing users with long-lasting, consistent performance

Application Range: Compatible with a wide range of antifreeze fluids (e.g., propylene glycol, ethylene glycol), this antifreeze tester automotive quickly measures freezing and boiling points to ensure vehicle performance. Easy to operate and providing accurate results, it is an ideal tool for vehicle maintenance
