Non-contact voltage tester testo 745
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.
With the testo 745 non-contact voltage detector, you can quickly and easily determine the presence or absence of voltage. In contrast to most other models on the market, it has a filter for high frequency interference signals, thus allowing a more reliable voltage indication. When it is determined that there is voltage, the instrument gives a clear visual and acoustic signal.
