3-Axis RF (Radio Frequency) Meter

3-Axis RF (Radio Frequency) Meter

The Sper Scientific 840047 3-Axis RF Meter is an essential tool for anyone needing precise and reliable measurement of electromagnetic field (EMF) radiation. Whether you're assessing environmental safety, troubleshooting wireless systems, or ensuring compliance, this meter delivers accurate readings across a wide range of frequencies.

This advanced device is expertly engineered to measure RF (Radio Frequency) electromagnetic field strength within a broad frequency spectrum of 50 MHz to 3.5 GHz. This extensive range covers virtually all common sources of RF radiation, including:

• Wi-Fi and LAN networks
• Cellular phone transmissions (2G, 3G, 4G, and some 5G bands)
• Radio and TV broadcasting towers
• Wireless cameras and microphones
• Smart meters and other IoT devices

Key Features & Benefits:

• 3-Axis Isotropic Probe: Unlike single-axis meters, the unique 3-axis probe provides truly non-directional measurement. This means you don't need to orient the meter in a specific direction to capture the full RF field, ensuring accurate readings from any angle and saving time in your assessments.
• Clear, Backlit LCD Display: Readings are presented in large, easy-to-read digits alongside a helpful bar graph for quick visual interpretation of signal strength. The backlit display ensures visibility in all lighting conditions.
• Versatile Reading Modes: Toggle between maximum (MAX) and average (AVG) readings to capture peak exposures or long-term baseline levels.
• Audible Alarms: Set customizable alarm thresholds to be notified immediately when RF levels exceed your predefined limits, ideal for continuous monitoring.
• Adjustable CAL Factor: For professional applications, you can set a specific calibration (CAL) factor to fine-tune measurements for particular frequencies, enhancing accuracy for specialized tasks.
• Data Logging Capability: Save and review up to 200 individual readings directly on the meter. This allows for historical data tracking, comparative analysis, and comprehensive reporting without the need for immediate manual transcription.
• User-Friendly Operation: Features such as auto-ranging simplify use, automatically selecting the appropriate measurement range. The auto power-off function conservates battery life, ensuring your meter is ready when you need it.
• Robust & Portable Design: Built for durability and convenience, the meter comes ready to use in a soft carrying case with a belt loop for easy transport.
