weight 1400g Manufacturer Part Number Does Not Apply Suit For DOT3 DOT4 DOT5 DOT5.1 SUPER DOT4 Vehicle Type Passenger Vehicle Warranty 1 Year Type Brake Fluid Boiling Point Tester Country/Region of Manufacture China Color Green Working Temperature 0?C ~50?C Storage Temperature -10?C ~50?C 0?C ~50?C undefined- Select - 100?C ~180?C(212?F ~356?F)?3% 180?C ~320?C(356?F ~ Brake fluid boiling point tester with 250mm goose neck probe provides flexibility of detection Protection of reverse polarity power connection. Step-by-step operating instruction on screen. Quickly diagnose boiling point with referenced minimum accepted values. Sampling paper not required cost saving. Brake fluids are hygroscopic meaning they absorb water from the atmosphere and that will appreciably lower the original point. If working temperature in brake system is higher than meaning boil point. The brake fluid will boil and producing a lot of vapor. Vapor cannot deliver the pressure from pedal to clipper. (so called vapor lock). Finally cause the brake system failure. If your country is in high moisture area. Brake fluid is getting more easy to absorb moisture and boil point brake down fast.We recommend let car owner to know that they had better change brake fluid every 20000 KM or 2 years. It?? all about safety and life. Specification: Applicable Brake fluid: DOT3 DOT4 DOT5 DOT5.1 SUPER DOT4 Boiling Point: 100?C ~180?C(212?F ~356?F)?3% 180?C ~320?C(356?F ~608?F)?5% Power: 12V DC minimum 10V DC Test Time: 60 seconds Working Temperature: 0?C ~50?C Storage Temperature: -10?C ~50?C NOTE: 1 Please do not touch test probe when test is done to avoid scalded. 2 Please do not re-use tested fluid or liquid. The fluid or liquid have been destructured and boiling point becomes lower down To discard the sampling fluid is strongly recommened . 3 Accepted boiling point about every kind of fluid please refer to user manual Packing List: DY23F * 1pcs 30ml Brake fluid injector * 1 pcs 50ml Beaker * 2pcs Carrying box * 1pcs User manual * 1pcs
