Δοκιμαστής τάσης Habotest HT89 — Μέτρηση τάσης AC/DC και έλεγχος συνέχειας

Habotest HT89 is a compact voltage tester for AC/DC voltage detection and continuity checks. It allows quick identification of live circuits, provides visual and audible indication of voltage presence, and includes a built-in flashlight for illumination. The device is lightweight and designed for routine troubleshooting, maintenance and on-site verification of electrical installations and equipment.

Advantages

The tester offers contactless AC voltage detection with simultaneous sound and light alerts, an LCD with bicolor backlight for clear status indication, and dedicated buttons for AC voltage measurement, flashlight and continuity/battery polarity checks. It features automatic power-off to save battery and a low-battery indicator. Its compact dimensions and 42 g weight make it easy to carry for electricians, technicians and DIY users.

Suitable for

• Quick detection of live AC circuits (12–300 V)
• Checking continuity in wiring and components
• Polarity detection of batteries and conductive checks
• On-site troubleshooting and maintenance of electrical equipment

How to use

Switch on the Habotest HT89 and select the desired function using the dedicated buttons: contactless AC voltage detection, AC voltage measurement or conductivity/positive battery polarity detection. Approach the probe end to the conductor or component to be tested; the tester will indicate voltage presence by sound and light and show status on the LCD with bicolor backlight. Use the flashlight button to illuminate the work area when needed. The device will switch off automatically after inactivity.

Recommendations

Before each use, verify the tester's operation on a known live circuit and replace the AAA battery if the low-battery indicator appears. Do not rely solely on contactless detection for complete safety verification; follow standard safety procedures and isolate circuits before carrying out hazardous work.
