Extech 480846 8GHz RF Electromagnetic Field Strength Meter
The Extech 480846 is a broadband RF field strength meter capable of measuring electromagnetic radiation from 10 MHz up to 8 GHz. With its isotropic 3-axis sensor, memory recall, alarm threshold, and multiple unit modes, it’s designed for RF “hot spot” detection, wireless system testing, and electromagnetic exposure monitoring.
Description
The 480846 RF Electromagnetic Field Strength Meter provides professionals with a versatile and sensitive platform to evaluate high-frequency electromagnetic fields. Its measurement range spans from 10 MHz to 8 GHz, with optimized sensitivity for common telecom, WiFi, and microwave bands. It employs a tri-axis (3-channel) non-directional sensor, meaning it can detect field strength regardless of orientation—no need to align the sensor precisely with the source.
When active, the meter can display instantaneous readings, maximum peaks, average values, or “max average” (the highest averaged reading over time). Users can set an audible alarm threshold to be alerted when field strength exceeds safe or specified levels. The meter also includes manual memory storage/recall for up to 99 measurements, aiding in field surveys or comparative analysis. It covers a broad dynamic range, supporting measures in electric field units (V/m, mV/m), magnetic field equivalents (µA/m, mA/m), and power density (µW/m², mW/m², W/m², µW/cm²). The device is compact and portable, powered by a 9 V battery, and housed in a rugged case for field operation.
