Shop for Microwave Leak Detectors

wonkee donkee power image Microwave leak detectors work by measuring the power of electromagnetic radiation, which is measured in mW/cm2 (milliWatts per centimetre squared).
5mW/cm2 limit for microwave radiation The accepted standard for maximum microwave oven radiation leakage is 5mW/cm2. Microwave leak detectors which do not give a numerical reading (analogue) will use this level to separate safe and unsafe readings.
microwave leak detector in use The reading is dependent on the distance between source and device. This means the microwave leak detector should be held a consistent distance away from the microwave source, usually advised at 5cm, but check individual manufacturer’s specifications before use.

Some microwave leak detectors have the sensor placed so it is the correct distance for a reading when another part of the device comes into contact with the microwave. This lowers the risk of human error and should produce a more reliable result.

frequency equals hertz A microwave leak detector generally has a stated frequency range, typically 3MHz to 3GHz, which includes microwave ovens, which usually have a frequency of 2,450MHz (2.45GHz) and should also include other radiating household items.
zero reading on microwave leak detector Most microwave leak detectors are factory calibrated before purchase – they cannot be recalibrated by the user. Calibration means comparing the readings of an instrument with set a standard to ensure the instrument’s accuracy.

Some microwave leak detectors can be zeroed before each use. This is where any background readings are cleared before the instrument is placed near the microwave source.
