Coolant Tester, Antifreeze Tester High Accuracy Dial Type Anti-Freeze Coolant Tester Car Battery Liquid Densitometer 6/12/24V

I live in the Rocky Mountains area where it can get really cold at night. My older Ford Explorer was going to spend the night outside my garage as I had a visiting guest whose shiny new car was in my garage, taking the place of the older Ford.The weather report showed a really cold cold-front was to pass thru my area. It was going to drop down to minus 20F. For peace of mind, I wanted to make sure that the antifreeze in thr Ford’s coolant system would handle the impending cold weather..Thus little device showed me that the antifreeze was in good shape. Good down well past minus 20F. A few bucks for peace of mind. It works easily. Nice. 5 stars. Good purchase.To be truthful, when I unscrewed the radiator cap I figured I was in good shape coolant-wise. The coolant was bright electric green in color. Still it was nice to confirm that the coolant was good down to atleast minus 45F. Piece of cake.For years my Ford had spent its nights in my garage in winter. So I hadn’t been concerned about the ability of its coolant to withstand cold, cold weather. Cheap way to a sense of well being.Driving 10 miles to the local auto shop and asking them to test the coolant wasn’t a great option. I would have tipped them the cost of this device and the engine would have been too hot to unscrew the radiator cap without causing a mess and loosing a bunch of coolant.

I recently purchased this coolant tester, and I am extremely impressed with its accuracy and ease of use. The build quality is solid, and the readings are clear and reliable. It quickly helped me determine the condition of my antifreeze, saving me from potential engine problems. The instructions were straightforward, making it simple even for someone without much mechanical experience. I also appreciate that it works with different types of coolant, adding to its versatility.Overall, this is a must-have tool for any car owner or mechanic. It’s a small investment that can prevent costly repairs. Highly recommended!

Works well but the only negative is the hose too short.

Worked out me and very easy to use.

Funciona perfecto 👌 RecomendadoHice pruebas en agua corriente, agua destilada, y por supuesto en refrigerante.

It Worked like it should.

Pésima calidad, al parecer me enviaron uno usado porque la bolsa venia llena de anticongelante.Las partes que lo unen tienen silicon mal puesto, en las fotos se pueden ver de lo que hablo.

economical way for quick check before winter .
