Masters Medical merged in 1991 from two companies Australian Medical Supplies and Masters Medical, both founded in the 1980s by Dr. Scott Porter. The company now supplies a wide gamut of medical products and services like Orthopaedic joint replacement systems, endoscopy and surgical equipment, including TENS machines hire and sales. Spectrum II is a Transcutaneous Electrical Nerve Stimulation (TENS) machine from Masters Medical.
Spectrum II are TENS units fabricated in the United States and among the most popular pain relieving devices in Masters Medical’s catalogues. These units come with an extended warranty of three year. With large size control knobs to set waveform intensity and duration of pulses, the Spectrum II TENS machines from Masters Medical is easy to use, especially for people who may not be able to use their hands due to arthritic pain. Spectrum II come with a dual channel that carries a variable pulse rate of normal and burst modes; the pulse width can also be modulated to treat the intensity of the pain. A flashing light indicates low battery for immediate recharging after prolonged use.
Self-adhering electrode with multiple applications are a standard inclusion with the Spectrum II. The wave-form and modulation specifications are much superior when compared to some other brands that are also supplied by Masters Medical. While no side effects of TENS such as dizziness, nausea or addiction have been noted, some users might experience skin irritation and redness, which is easily solved by changing the electrodes or gel.
