About this product
This Faithfull detector checks for electromagnetic field leakage from microwave ovens and other electrical items, useful in commercial kitchens, catering facilities and homes. It is straightforward to use, requiring no technical expertise, and is aimed at anyone needing to verify microwave safety quickly, including in settings with vulnerable individuals. An analogue needle display gives instant visual feedback, with a green zone showing safe levels and a red zone warning of potential leakage. It covers a frequency range of 3MHz to 3GHz, so it can also test mobile phones and cameras. The unit needs no battery, so it is always ready to use. It measures 45 x 100 x 22mm, weighs around 38g, and operates in temperatures from 0°C to 40°C, making it convenient for engineers and facilities staff to carry.
