Voltage tester Högert Technik HT1S981 for 100–500 V, 150 mm probe length

Högert Technik HT1S981 is a handheld voltage tester for detecting alternating voltages in the 100–500 V range. The device features a 150 mm probe length that allows direct contact testing of electrical circuits, sockets and wiring. Its compact form factor and simple operation are intended for quick voltage checks during maintenance, troubleshooting and installation in residential and commercial electrical systems.

Advantages

The voltage tester provides a clear, contact-based indication of AC presence within the specified range and is designed for straightforward single-handed use. A 150 mm probe gives access to terminal points and recessed sockets while reducing the need for additional extension tools. The tool’s compact dimensions make it easy to carry in a toolbox or pocket and to use in confined spaces.

Suitable for

• Quick voltage verification on outlets and switches
• Testing wiring and terminal connections during installation
• Troubleshooting electrical faults in residential and light commercial systems
• Routine maintenance checks by electricians and technicians

Key specifications

• Voltage detection range: 100–500 V AC
• Probe length: 150 mm for direct contact testing
• Handheld form factor suitable for single-handed operation
• Designed for contact testing of circuits, outlets and wiring

How to use

Before testing, ensure the tester is in good condition and follow applicable safety procedures, including switching off equipment where possible and using appropriate personal protective equipment. For contact testing, insert the probe tip to make secure contact with the conductor or terminal to be checked and observe the tester’s indication of voltage presence. When testing outlets, access the live contact carefully and avoid touching exposed conductors. After use, store the tester in a dry place and inspect the probe and insulation for damage before the next operation.

Usage recommendations

The tester is intended for professional and skilled-user applications where contact testing is appropriate. Do not use the device beyond its specified voltage range. If insulation or probe damage is visible, do not use the tester. For non-contact voltage detection or measurements outside the stated range, use instruments designed for those functions.
