Receptacle Tester Habotest HT107D Contact CAT II LCD Display

The Habotest HT107D Contact Receptacle Tester CAT II with LCD Display is a compact portable device for checking wiring and basic voltage presence at mains sockets. Designed for CAT II overvoltage environments, the tester combines a readable LCD screen with a small footprint (65mm × 62mm × 58mm) to allow quick identification of voltage and simple fault patterns at wall outlets. It is intended for field technicians, electricians, and maintenance personnel who need a straightforward contact test instrument for standard single-phase receptacles.

Advantages

The tester provides direct contact measurement with an LCD display for clear numeric and status indications, reducing ambiguity compared with purely LED-based testers. Its CAT II rating aligns it with typical installation and appliance-level environments, and the compact housing makes it easy to carry and position in crowded panels or sockets. The intuitive front-panel display and straightforward probe/contact arrangement allow efficient spot checks and rapid verification of socket conditions.

Suitable for

• Quick verification of mains voltage presence at single-phase wall sockets
• Basic wiring fault detection during installation or maintenance
• Portable field checks by electricians and service technicians
• Routine outlet inspections in residential and light-commercial settings

When it may not be suitable

This contact tester is intended for CAT II environments and basic receptacle checks; it is not designed for high-energy distribution testing, complex multi-phase diagnostics, or situations requiring insulation resistance, earth loop impedance, or detailed harmonic analysis. Users needing advanced measurement functions, higher overvoltage categories, or non-contact voltage detection should consider more specialized instruments.

Key specifications

• Measurement method: direct contact receptacle testing with display readout
• Overvoltage category: CAT II (suitable for appliance and installation-level circuits)
• Display: LCD for numeric and status information
• Dimensions: 65 mm (width) × 62 mm (depth) × 58 mm (height)
• Form factor: compact portable hand-held tester

How to use

Insert the tester into the mains socket or make the specified contact points as described in the user manual, then observe the LCD display for measured voltage values and status indicators. Perform tests with the supply energized and follow safe working practices: ensure hands are dry, use protective equipment when required, and avoid contact with live conductors beyond the instrument’s intended contact points. Interpret the displayed readings according to the device legend to identify common wiring conditions such as correct polarity, missing earth, or open neutral.

What to consider before purchase

• Verify that CAT II is appropriate for your intended work environment
• Confirm the tester’s display and measurement capabilities meet your diagnostic needs
• Check compatibility with the socket types and local mains voltage used at your site

Usage recommendations

Use the Habotest HT107D for routine outlet spot checks and quick confirmation of voltage and basic wiring status. For safety, combine the tester’s readings with visual inspection and, when necessary, additional testing instruments for more advanced or high-energy tasks.
