Description

NISSEI RS 502 SWR Meter

The NISSEI RS 502 SWR Meter is an essential tool for accurate measurement of SWR and power in the 1.8~525 MHz frequency range. Designed for use in amateur radio, broadcasting, and RF testing, this meter offers reliable performance for both low and high power systems. With up to 200W power measurement, it provides comprehensive functionality for professionals. The large analog meter with a backlit display ensures visibility even in low-light conditions, making it perfect for use in the field or lab.

This meter features a high accuracy rating: ±10% for the 5W range and ±5% for the 20-200W range, making it ideal for precise measurements across a wide power range. The minimum power requirement of 3W allows for testing both low and high-power devices. With SO-239 (UHF/N Female) connectors and a 50Ω impedance, it is compatible with a wide variety of RF systems, providing minimal insertion loss at 0.1dB.
