Microwave ovens use electromagnetic waves at 2450 MHz to heat food. Those waves should stay inside, contained by the oven's metal cavity — which acts as a Faraday cage — and by the door seals. Over time, though, worn door seals, a door that no longer closes fully, loose hinges, corrosion or knocks can let the waves escape. The CEM GD-3806 makes that invisible hazard visible.
Microwave leakage is a safety issue to be taken seriously. While the oven is running, high-frequency radiation escaping from a damaged point can pose a risk, particularly to anyone standing close by.
These leaks cannot be seen. An oven being "only a bit old" does not mean it is safe. The only way to be certain is to use a professional measuring instrument.
Some simple devices on the market only light up to give a vague "leak / no leak" warning. The CEM GD-3806 is a professional measuring instrument and gives you a numerical value.
Digital LCD: the large digital display shows the leakage level clearly in mW/cm², the international standard unit. That removes the guesswork — not "there is some leakage" but "there is exactly 3.2 mW/cm² of leakage".
International safety limit: 5.0 mW/cm². Most international health and safety bodies set the leakage limit for microwave ovens at 5.0 mW/cm², and the CEM GD-3806 works to that threshold. The moment this dangerous level is exceeded, the instrument warns you both audibly and visually.
The instrument is equipped with features that make it easy to use for everyone, from service engineers to end users.
This is a valuable tool not only for technical service departments but for anyone who takes safety seriously.
