Customer Questions & Answers

Shouldn't Its Max Reading Be Higher than 1.99 mW/cm2

The energy carried by microwave and radio wave radiation is expressed in terms of milliwatts per square centimeter. A Federal standard limits the amount of microwaves that can leak from a microwave oven throughout its lifetime to 5 milliwatts (mW) of microwave radiation per square centimeter at approximately 2 inches from the oven surface (5mW/cm2). After reading the description of the device, it says it reads from 0 to 1.99mW/cm2. But shouldn't this device's max reading read higher than 1.99mW/cm2? I mean at least to 5mW/cm2 right? or am i missing something? I am an 8th grade school teacher and i've written a lesson plan where my students and I are doing a STEM Science experiment where we examine the power density of their various cell phones, from various distances while texting and calling and compare our data between cell phone make and cell carrier. I know the power density readings will be very small for cell phones. But for microwaves, I figured this particular disometer should read higher than 1.99. Thanks in advance for your help!

Customer Reviews

Microwave Leakage Detector is rated 5.0 out of 5 by 1.
Rated 5 out of 5 by from Simple to use and effective Very easy to use and simple instructions. Gave me peace of mind knowing my microwave was not emitting too high levels of radiation. Simply turn device on, hold in front of microwave while in use at varying angles and distance, the reading appears on the screen and an alarm beeps to alert you. You can freeze the highest reading to lock it in with a push of a button. Good to use especially if you have an older microwave.
