Digital Microwave Oven Leakage Meter

Direct and easy to use and see.

Bought this to test an old microwave. The readout and operation of this meter is simple and does exactly what you want it to do. (A note – this only detects microwave oven radiation – not good for magnetic or electrical radiation). Sure enough my old oven was emitting a dangerous level of microwave radiation, apparently from worn door seals. Got a new Panasonic microwave with extra goodies. Tested it right out of the box and it was worse than my old one! Took it back and warned them that this was a dangerous oven with high levels of microwave radiation. They probably just put it back on the shelf. Finally got a cheaper and somewhat smaller Emerson, tested it and it worked great – very low emission. This microwave detector has already paid for itself as far as I’m concerned.

Excellent for Price

I had removed and disassembled a microwave oven door in order to replace a broken handle and wanted some level of assurance that the oven was not leaking dangerously after the repair. In my case, the unit gave readings between 1/100 and half a milliwatt per square centimeter when moved around the over door seals and across the glass at a distance of about 2″. These readings are well below the FDA limit of 5 milliwatts per square centimeter where the unit is supposed to beep. So it seems to be pretty sensitive – and, from the last review (where the unit did beep), also able to detect higher, more dangerous levels of leakage. It probably deserves 5 stars but there is no way to absolutely validate its accuracy, so I am giving it four.

Good product, initial problems resolved

I was concerned that my microwave oven door might have been damaged, so this meter seemed to be good way to check. It arrived very promptly, and the back of the case had the imprinted message “Please read manual for safety” – except… there was NO manual, NO instructions, NO warranty information, and NO response to my inquiry through Amazon marketplace email. The meter showed nothing but flat zero readings until I enlisted the aid of a neighbor who is a PHD in physics and electronic engineering. He was able to do some razzle-dazzle to get the meter to respond, but I am not impressed with the product or the seller.

Note: Seller did contact me 1/4/2012, very concerned that they had not received my inquiry through Amazon Marketplace. They have forwarded the instructions by email, and I cannot blame them for product issues they had no knowledge of – hard to fix a problem that nobody has told you about! Would buy again based on the effort they made to contact me.
