The Bio Protech TENS 1000 was inspired by demands for an affordable yet user-conscious pain control device. User-driven, these units feature a wide array of output combinations to help get the settings "just right". With times ranging from 15 or 30 minutes to continuous mode, users can pick the setting that's right for them. In addition, this TENS device also feature three modes: B(Burst), N(Normal), and M(Modulation). The pulse rate, pulse width, and amplitude are adjustable to lessen acute pains due to an accident or chronic conditions such as arthritis or other joint and muscle conditions.
