Carbon monoxide is a particularly dangerous gas. It is colorless, it is odorless and above all it is lethal. That's why it is so important that CO checks are carried out when a gas heating or boiler is being serviced or installed. This not only ensures that the heating or boiler is working properly it also helps to prevent tragic accidents that occur as a result of carbon monoxide poisoning.,

Testo 745 Non-Contact Voltage Tester, 12 - 1000 volt, Visual and Acoustic 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. 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.,
