Voltage tester EMOS VT-320 for 220V AC and 12V DC

The EMOS VT-320 is a handheld voltage tester for detecting AC and DC voltages in ranges commonly used in building and low-voltage installations. It accepts voltages from 12 V to 690 V and provides optical and acoustic indication when voltage is present. The tester is battery-powered (9 V battery included) and is intended for phase and sequence detection, continuity checks and basic voltage verification in both AC and DC systems.

Advantages

The device supports a wide voltage range (12–690 V) and measures both AC and DC voltage, with optical and acoustic signaling for clear indication. It includes functions for phase identification and sequence detection, as well as continuity measurement. The compact, handheld design and included 9 V battery allow immediate use in the field.

Suitable for

• Electricians performing on-site voltage checks
• Technicians troubleshooting low-voltage DC systems (e.g., 12 V, 24 V)
• Verification of mains and industrial voltages (e.g., 120 V, 230 V, 400 V, 690 V)
• DIY users who need basic continuity and presence checks

How to use

Install the supplied 9 V battery, select the appropriate test mode if applicable, and apply the test probe to the conductor or contact to be checked. Observe optical and acoustic signals to determine presence of voltage, polarity and, where applicable, phase sequence. For continuity checks, connect the tester between two points of the circuit and listen for the acoustic signal or check the optical indicator.

Usage recommendations

Before testing, ensure that the tester and its probe insulation are intact and that you follow applicable safety rules. Do not rely solely on the tester for complete safety; verify with appropriate procedures and personal protective equipment when working on live circuits.
