Extech EMF300 Microwave Leakage Detector
The Extech EMF300 Microwave Leakage Detector is a compact and reliable tool designed to measure high-frequency radiation emitted from domestic and commercial microwave ovens. With precise sensitivity, it ensures safety by detecting radiation levels up to 1.999mW/cm². If levels exceed 1mW/cm², an audible alarm provides an instant warning. Its clear LCD screen allows easy data interpretation, making it suitable for both professional and home use.
Accurate Detection and User-Friendly Operation
This microwave leakage detector delivers accurate results with a measurement precision of <2dB at 2.45GHz ±50MHz. The peak hold function lets users capture the highest recorded value with a single button press, ensuring no important data is missed. The over-range indicator displays “OL” if the detected levels exceed the device’s range, alerting users instantly.
Versatile Measurement and Practical Design
Designed to handle a wide frequency range, the Extech EMF300 can also reference EMF levels between 30MHz and 3GHz. While not calibrated for precise readings outside its main range, it provides useful reference data. Compact and lightweight, it fits comfortably in hand and is easy to transport. Powered by a standard 9V battery, it remains highly portable for on-site testing.
Built for durability, the Extech EMF300 meets CE certification standards and includes a two-year warranty. Its robust construction and precise detection capabilities make it an essential tool for microwave leakage safety testing in various environments.
