Feature: 1. Accurate Measurement: This power meter offers accurate measurements with a ranges of 0.5W to 120W (up to 200W in certain modes). For prolonged FM, AM, and CW modes, it is recommended to stay below 120W, while SSB mode allows for higher power options. 2. OLED Display: Featuring a 128*64 OLED screen, the SWR meter directly displays forward power, reflected power, antenna power, SWR, battery voltage, and other parameters. The clear and comprehensive display ensures easy monitoring and analysis. 3. High SWR Alarm: The meter supports a high SWR alarm function. When the SWR exceeds 2.5 but remains below 3, the intermittent alarm will sound. If the SWR exceeds 3, the alarm will sound continuously, alerting users to potential issues. 4. Indicator Lights: The meter is equipped with indicator lights for easy status identification. The red light indicates charging, the green light indicates a fully charged battery, and the yellow light indicates the working status. 5. Reliable Quality \u0026 Built-in Battery: Crafted with high-quality aluminum alloy, it is lightweight, compact, and has nice durability. It is designed for portability and convenience. The built-in 1000mAh battery ensures long battery time, making it perfect for on-the-go use. 6. Designed for Amateur Enthusiasts: This digital power meter is specifically designed for amateur radio enthusiasts. It is suitable for anyone interested in measuring and optimizing antenna performance. Whether you are a beginner or an experienced user, this meter provides the necessary tools for enhancing your radio experience.
