Brake Fluid Tester DOT3 DOT4 DOT5.1 For Car Maintenance

This Brake Fluid Tester Measures Water Content In DOT3, DOT4, And DOT5.1 Brake Fluid Using Electrical Conductivity Change, Built For Car Owners And Home Mechanics Who Want To Check Fluid Condition Before It Affects Braking. The Probe And Housing Are Made Of Impact-Resistant And Scratch-Resistant ABS, So The Pen Withstands Repeated Handling In A Home Garage, Not Just A Professional Workshop. You Insert The Metal Probe Into The Fluid For 3 Seconds, Wait For The Display To Stabilize, And Read A Numeric Moisture Value Instead Of Guessing Whether The Fluid Is Still Usable. The Tester Gives A Clear Result: Green Backlight At 0% To 2% Means The Fluid Can Stay, Yellow Backlight With A Slow Buzzer At 2% To 3% Means Plan A Replacement, And Red Backlight With A Fast Buzzer Above 3% Means Change The Brake Fluid Now. Unlike Basic Testers That Only Offer A Pass Or Fail Light, This Pen Shows Actual Percentage Values, Has Selectable Fluid Types, And Includes Both Visual And Audible Alerts. It Is Not For Use On DOT5 Silicone Fluid. Use It Only On DOT3, DOT4, And DOT5.1. The Metal Probe Must Be Clean And Dry Before Each Test. This Tester Is Not A Substitute For A Full Brake System Inspection By A Qualified Mechanic, And It Does Not Measure Fluid Age Or Boiling Point. Specifications:
