Voltage Tester Tvardy model 182mm for 100–250V circuits

Tvardy Voltage Tester model with a 182 mm probe is a handheld tool designed to detect presence of alternating current (AC) voltage in the 100–250 V range. It combines simple non-contact and contact indications to help electricians and DIY users quickly verify whether outlets, switches, cables or fixed wiring are live. The tester is compact and intended for fast checks during maintenance, troubleshooting and installation preparation.

Advantages

The tester offers a straightforward indication method suitable for quick on-site checks without complex setup. Its 182 mm probe length provides safe reach into outlets and terminal areas while minimizing user exposure. The device covers the common household and light industrial AC voltage range of 100–250 V and supports both contact and non-contact detection modes for flexible verification of live conductors.

Suitable for

• Verifying presence of AC voltage in household sockets (100–250 V)
• Quick checks of switches, junction boxes and visible wiring
• Pre-maintenance safety confirmation for electricians and technicians
• DIY electrical troubleshooting and basic circuit testing

When it may not be suitable

This tester is designed for detecting the presence of AC voltage within the 100–250 V range and is not intended for precision voltage measurement or for use on low-voltage electronics, high-voltage lines, or DC-only circuits. It should not replace insulation testers, multimeters, or dedicated phase/ground testers when detailed diagnostic data or measurement accuracy is required.

Key specifications

• Probe length: 182 mm
• Voltage detection range: AC 100–250 V
• Detection modes: contact and non-contact indication
• Application: handheld voltage presence tester for wiring, sockets and switches

How to use

Hold the tester by the insulated handle and use the probe tip to approach or contact the conductor, socket pin or terminal you want to check. For non-contact detection, bring the probe close to the insulated cable or socket opening and observe the indicator; for contact detection, carefully touch the conductor while following safe working practices. Always follow standard safety procedures: de-energize when possible, wear appropriate personal protective equipment, and confirm results with additional testing tools if uncertainty remains.

What to consider before purchase

• Ensure the 100–250 V detection range matches the voltages you need to check
• Consider whether you need precise voltage measurements or additional test functions not provided by this tester
• Check compatibility with your typical working environment (indoor use, accessible wiring and sockets)

Usage recommendations

Use the Tvardy 182 mm tester for rapid presence checks of household and light commercial AC circuits, and always corroborate findings with a multimeter or specialized tester when performing repairs or verifying safety-critical installations.
