## Summary description

Handheld Brake Fluid Tester Habotest HT662 with digital display and auto-ranging for testing DOT and glycol-based brake fluids. Detects water content in brake fluid to assess boiling point degradation and maintenance needs. Portable tool for garages, vehicle inspections and DIY car service to check fluid condition quickly and prevent brake system failure.

## Long description

Habotest HT662 brake fluid tester is a handheld instrument designed to measure the percentage of water present in DOT and glycol-based brake fluids. The device uses a sensitive probe and an LCD digital display to show readings in the 0%–4% range, with visual (red/green backlight) and audible alarms to indicate critical moisture levels. Its compact ABS housing, pocket clip and automatic 5-minute shutoff make the tester convenient for garages, vehicle inspections and DIY car maintenance. The tester is powered by two 1.5V AAA batteries, and a low-battery indicator notifies when batteries need replacement.
Advantages
Habotest HT662 provides quick on-site assessment of brake fluid condition without requiring laboratory equipment. The clear digital readout and combined light and sound alarm simplify interpretation of results, while the sensitive corrosion-resistant probe ensures reliable contact with the fluid. Lightweight construction and automatic power-off improve portability and battery life, and included batteries and a pocket clip allow immediate use in workshop or roadside checks.
Suitable for
Periodic maintenance checks of passenger cars and light commercial vehicles
Pre-inspection testing during vehicle safety inspections
Garage technicians performing brake system diagnostics

How to use
Turn on the Habotest HT662 and select the appropriate brake fluid type if required. Remove the protective cap and immerse the probe into a small sample of brake fluid so that the sensing area is fully submerged. Wait for the LCD reading to stabilise; the device will show the percentage of water content and trigger the appropriate backlight color and audible alarm if thresholds are exceeded. After measurement, wipe the probe clean, replace the cap and switch the tester off. The unit will also shut off automatically after five minutes of non-use to conserve battery power.
Usage recommendations
For accurate measurement, test a small, representative sample of brake fluid taken from the reservoir or bleed point; avoid testing fluids contaminated with dirt or metal particles. Replace brake fluid if water content exceeds the recommended safe range (commonly above 3%), and follow vehicle manufacturer service intervals. Store the tester in a dry place, remove batteries if the device will not be used for extended periods, and periodically inspect the probe for corrosion or damage.
