The Nissei RS-70MAX SWR & power meter is a commercial-grade, high-precision digital diagnostic instrument precision-engineered to monitor transmission line efficiency, structural impedance matches, and real-time peak envelope power curves. Driven by an advanced microprocessor tracking core, this premium testing terminal eliminates the need for tedious manual calibration routines, enabling operators to read multiple active metrics instantly through an intuitive single-key SWR measurement design. It serves as an essential infrastructure asset for electronics repair benches, marine communication hubs, tactical military field kits, public utility installations, and high-volume B2B radiocommunication accessory wholesale networks looking to source cutting-edge digital instrumentation.
The advanced internal RF core of the RS-70MAX delivers exceptional broad-spectrum signal tracking across a wide High Frequency (HF) and low VHF bandwidth, operating continuously over a versatile frequency range of 1.6-60MHz with factory-calibrated reference precision set directly at 144/50MHz bounds. Calibrated to measure power thresholds spanning 0-150W, the specialized logic board is capable of measuring a comprehensive suite of modern wave vectors. In standard MAX OFF mode, it tracks CW, FM, and FDMA signals with ease, while toggling to the specialized MAX ON mode unleashes high-speed tracking electronics to capture the complex envelope peaks of SSB, AM, and digital DMR waveforms. With an incredibly low insertion loss rating where the losses are 0.3dB or less, it safeguards active signal path integrity across all telemetry lines.
Housed inside a highly compact, lightweight, and vibration-dampened alloy chassis measuring just 70 x 78 x 30mm and registering a net structural weight of 220g (without batteries), this pocket-sized console features an expansive, high-contrast LCD display for easy reading that broadcasts real-time telemetry data regarding active system status. For ultimate versatility during long shifts or off-grid remote operations, the power subsystem is built on a highly adaptable hybrid grid. The terminal operates with AAA batteries or with external USB-C power using a standard USB-C 5v. DC connector input port, and seamlessly handles the internal tracking profiles of both primary non-rechargeable cells and high-cycle rechargeable batteries. Terminated with heavy-duty PL / PL (UHF Female) interface ports to maintain an unyielding nominal impedance of 50 ohms, this turnkey metric package ensures immediate system alignment and absolute field deployment readiness.
