Brake Fluid Tester pen

Why do we need Brake fluid tester pen ? Accurate Oil Quality Check Pen Universal Brake Fluid Tester

1. The inferior brake fluid causes the brake failure easily,thereby lead to an accident

2. The Brake fluid is related to the life of Brade pads, if one doesn’t take it seriously, the life of brake pads is worried.

Brake fluid detection pen is based on the change in conductivity to determine the moisture change brake fluid. It shows clearly the extent of moisture contained by the light-emitting diode, high moisture content will lead to lower boiling point, and affect braking performance. Red indicates the brake fluid needs immediate replacement, green represents good condition,  yellow indicates the state is acceptable but soon replaced.

Features: Auto Liquid testing Brake Fluid Tester pen 5 LED indicator display for DOT3/DOT4

1. check the car brake oil quality

2. 5 LED lights display the percentage of moisture content in brake fluid.

3. Press the button for power on, green LED will light up.

4. Insert the tester into reservoir for a second , then the results will be indicated correctly by LEDs.

5. Testing for DOT 3, DOT4 brake fluid

6. Auto power off, Supports 1 LR03 AAA batteries (not included)

1. The green LED lights = water content in the brake fluid H2O <1.5%, brake fluid qualified

2. The yellow LED lights = brake fluid water content H2O = 1.5% to 3%, can continue to use, test again six months later

3 .The red LED lights = water content in the brake fluid H2O> 3%, can not continue to use the brake fluid needs to be replaced

Red LED: change brake fluid

4.LED red flashing: battery replacement

5.LED yellow: low moisture content, check again in six months

6.LED green: brake fluid lines / cell row

Technical parameters: 12V Digital Battery Alternator Tester with 6 LED Lights Display Battery Testers with Brake Fluid Tester For Car Motorcycle

Green: Battery OK, that is, brake fluid does not contain water

Green / yellow: brake oil in water content of less than 1%, better brake fluid performance, ease of use.

Green / yellow / yellow: brake oil in water content of about 2%, brake fluid can continue to use.

Green / yellow / yellow / red: brake oil in water content of about 3%, the proposed replacement of brake fluid.

Green / yellow / yellow / red / red: brake oil in water content of at least 4%, the brake fluid must be replaced immediately responsible for very dangerous.

The Metrics is accurate to 1%,  it can help you to know the situation of Brake Fkuid more clearly .

Our Brake Fluid Tester is with Nickel-plated sensor , it restrains the corrosivty of brake fluid , the exterior uses ABS plactis + PE material , it is more anti-corrosion than normal PE material with testing . The normal one is with stainless sensor , it is easy corroded and can not use long time .

Step 1 : Open car’s front cover

Step 2 :  Find the brake Oil tank mouth

Step 3 :Dip test probes and read the Led lights

Step 4: Recover the car’s front cover
