Ensure your vehicle's cooling system stays corrosion-free and efficient with the ET5676 Antifreeze pH Meter - a professional tool designed to accurately measure the pH level of antifreeze and coolant solutions.

With EV vehicles as coolant decays, the acidity can increase, causing corrosion within the cooling system. This tester allows for quick testing of the coolant PH.

• Most automotive coolants should have an acidity level greater than 7.5. Check manufacturer specifications for suitable PH range.
• Measuring range: 0.00 - 14.00 PH | Resolution: 0.01PH | Accuracy: /- 0.1PH
• Operating temperature: 0 - 50¡C (Auto temperature compensation: 0 - 50¡C)
3x LR44 batteries (included)
