Voltage Tester Proxxon PR22390 — 3.0 × 0.5 mm VDE probe, 220–250 V

Proxxon PR22390 is a compact voltage tester for detecting AC mains and circuit voltages in the 220–250 V range. The tester is fitted with a VDE-rated probe tip measuring 3.0 × 0.5 mm for reliable contact testing of terminals, screws and conductors. Its compact form factor and single-function design make it suitable for electricians and competent DIY users who need a straightforward tool to verify presence of live voltage in household and light-commercial installations.

Advantages

The VDE-rated probe ensures compliance with safety standards for insulated tools and provides a defined contact geometry for consistent measurements. The narrow 3.0 × 0.5 mm tip allows easier access to tight terminal spaces and screw heads. The tester is designed for quick, one-handed checks and minimal setup, enabling faster verification of live circuits. Its simple operation reduces the chance of user error when confirming presence or absence of AC mains voltage.

Suitable for

• Quick checks of household socket and lighting circuits
• Verifying voltage at terminal blocks and switch contacts
• On-site troubleshooting during light-commercial electrical maintenance
• Use by electricians and experienced DIYers for safety verification before work

Key specifications

• Measurement range: AC 220–250 V
• Probe tip: VDE-rated, 3.0 × 0.5 mm
• Function: presence of AC mains voltage detection
• Form factor: compact, handheld tester for contact testing

How to use

Hold the tester by its insulated body and place the probe tip in contact with the conductor or terminal to be tested. Ensure the tester’s reference contact or body contact is made as required by the device design. Observe the tester indication to confirm the presence or absence of AC voltage within the 220–250 V range. Do not use the tester on circuits outside its specified voltage range and avoid relying on it for precision voltage measurement—use it only to detect live voltage.

Usage recommendations

Before use, inspect the probe tip and insulation for damage and do not use if protective insulation is compromised. Always follow local electrical safety rules: isolate power where possible before working, use appropriate personal protective equipment, and verify with a secondary test method if necessary. Store the tester in a dry place and keep out of reach of untrained persons.
