Description
The Nissei RS-70 SWR 1.6–60 MHz Wattmeter 200W is a compact and reliable RF measurement instrument designed for accurate monitoring of Standing Wave Ratio (SWR), Forward Power, and Reverse Power across HF communication systems. Engineered for radio operators, RF technicians, and antenna setup applications, this digital wattmeter helps maintain efficient signal transmission and improve antenna performance.
Operating within a frequency range of 1.6–60 MHz, the RS-70 is suitable for HF radio communication, antenna testing, and RF performance verification. With a measurable power range of 0–200W and maximum power capacity of 200W, the device enables accurate power monitoring for reliable communication system operation.
The meter provides dependable performance with an accuracy class of ±5%, delivering stable measurement results during RF analysis. Its integrated backlit LCD display allows clear visibility of SWR and power values in different operating conditions.
Designed for convenience and portability, the RS-70 supports flexible power operation using 2 × AAA batteries or a Micro USB power input, making it suitable for both portable and bench-top use. The standard SO-239 connector ensures compatibility with common RF equipment, while the 50 Ohm impedance design supports optimized antenna matching and reduced reflected power.
With a compact form factor of 70W × 78H × 30D mm, the RS-70 offers a practical solution for communication testing, RF monitoring, and antenna tuning applications.
