Van den Hul The Polarity Checker

This is a unique device for fine-tuning audio installations. It enhances its resolving capabilities by minimizing its residual ground currents.

• Multi-tasking: it works as a voltage, phase and cable-interruption checker for domestic appliances.
• The LCD screen shows the values by touching the equipment-to-be-checked with the POLARITY CHECKER screwdriver blade.
• Measures AC 12V to 230V and DC in 12, 36, 55, 110 and 220V. It can also indicate the presence of electrical stray fields.
• Do not use with AC or DC voltages exceeding 250 Volts!
• Very safe and also very sensitive: Its leakage current is less than 3µA.
• Comes with carefully detailed instructions describing how to minimize residual ground current.
