testo 745 - Non-contact voltage tester
- Gama de medição até 1000 V
- Com classe de proteção IP67 (resistência a salpicos e sujidade)
- Configurável para a identificação de fases ou a indicação de tensão
- Indicação ótica e acústica
- The testo 745 non-contact voltage tester is ideally suited for fast initial checking of any suspected fault sources. It filters high-frequency interference signals and has a two-stage sensitivity setting.
The testo 745 non-contact voltage tester means you can quickly and easily determine voltage or de-energization. In contrast to most other models on the market, it has a filter for high-frequency interference signals which enables reliable voltage indication. If voltage is determined, the instrument gives a warning via a clear visual and acoustic signal.
The sensitivity of the instrument can be set in two stages: stage 1 for phase detection, stage 2 for voltage indication. The integrated torch also enables you to work safely in dark surroundings. In addition, the testo 745 voltage tester is both waterproof and dustproof according to IP 67. Dados técnicos gerais
