HT INSTRUMENTS HT10 detetor de tensão de 2 polos CAT IV 1000V AC/DC 1010850

Electricians and maintenance technicians working on industrial and building installations need a reliable voltage tester that can handle high-energy circuits safely. The HT INSTRUMENTS HT10 is a 2-pole voltage tester with CAT IV 1000V rating, suitable for testing AC and DC voltages from 12V to 1000V. It provides clear LED indication of voltage levels and an LCD for exact readings, resistance, and frequency. The tester also offers continuity testing, phase sequence testing, single-pole phase testing, and RCD trip testing, making it a versatile tool for daily electrical work.

Why choose it

The HT10 combines high safety with practical features. Its CAT IV 1000V rating allows safe testing in low-voltage installations, and the dual display gives both quick level indication and precise measurements. The built-in flashlight and IP64 protection make it suitable for use in harsh environments.

Ideal use cases

• Verifying absence of voltage before working on circuits
• Testing continuity and resistance in wiring and components
• Checking phase sequence in three-phase systems
• Tripping RCDs to test their functionality
• Locating phase conductors in sockets and switches

Good to know

The HT10 complies with EN 61243-3:2014, the standard for two-pole voltage detectors. It uses two AAA batteries, which are not included. The removable 2mm probe tip adapter allows access to small terminals.
