Short Product Description

Stop guessing with old-fashioned indicator lights. The Habotest HT91D+ is a 2-in-1 smart voltage tester and screwdriver that gives you precise, real-time voltage readings on a clear LCD screen. From checking household sockets to testing batteries and detecting wire breaks, this professional-grade tool ensures safety and accuracy for electricians and DIY enthusiasts alike.

Key Features

Smart LCD Display: Provides clear digital voltage readings (12-300V) instead of just a simple indicator light, eliminating guesswork.
2-in-1 Tool Design: Features a hardened, removable screwdriver bit (Cross/Slotted) so you can test and tighten screws with one tool.
Non-Contact Voltage (NCV): Safely detects the presence of AC voltage through insulation, protecting you from accidental shocks.
Live/Null Wire Distinction: Instantly identifies Live wires (red screen + fast beep) and Null wires (green screen), making wiring jobs safer.
Battery Polarity Detection: Easily identifies the positive pole of batteries (<36V) with a specific display indicator.
Breakpoint Detection: Simply slide the pen along a cable; the alarm stops exactly where the internal wire is broken.
Data Hold Function: Smartly records the last 2 measurement values for review after testing.
Built-in Flashlight: A bright LED light illuminates your workspace, perfect for dark electrical cabinets or behind desks.
