Benning DUSPOL digital Two-Pole Voltage Tester, ISO Calibrated, CAT III 1000 V / CAT IV 600 V, LCD, Vibration, Acoustic 50263-ISO

The Benning DUSPOL digital stands out with its ISO calibration and dual-indication system—LCD, acoustic, and vibration—making voltage detection unmistakable even in noisy or bright environments. Unlike basic testers, it combines a two-pole voltage tester, continuity tester, phase rotation indicator, and single-pole phase tester in one rugged tool.

Highlights

• ISO calibrated for documented measurement reliability
• CAT III 1000 V / CAT IV 600 V safety rating
• LCD display with acoustic and vibration indication
• Switchable load for RCD trip testing (approx. 30 mA)
• IP65 protection against dust and water jets

In daily use

Measure AC and DC voltage from 6 to 1000 V without pressing a button—just touch the probes. The high-impedance mode prevents RCD tripping, while the low-impedance mode can deliberately trip RCDs to verify their function. Continuity testing is confirmed by both sound and light, and the phase rotation test helps ensure correct motor wiring. The 4 mm probe tips fit standard test accessories.
