Brake fluid test unit BFT 320

Order no

Brake fluid is hygroscopic, which means that it absorbs water over the course of time, thus causing the boiling point to drop (risk of vapor lock). That is why it needs to be checked regularly and, if necessary, replaced.
The particularly inexpensive ATE BFT 320 allows measurement of the boiling points of all glycol-based brake fluids ( DOT 3, DOT 4, DOT 5.1) with the same precision as in a laboratory.
The ATE BFT 320 is an extremely practical tester with a 12-Volt power supply. This means that it is simple to perform the measurement at the expansion tank in the vehicle.

A specimen vial and a pipette are supplied to allow measurements to be performed away from the vehicle.
The simple menu guidance for users is a highlight of the ATE BFT 320. Measurement takes only around 30 seconds and the measured value is shown on a digital display. A recommendation as to whether to replace the brake fluid is then shown. This means that it is no longer necessary to change brake fluid merely on suspicion.
