Active device is essential for reliable installation of background music and paging systems in residences, offices buildings and public areas. Avoid costly service calls and amplifier damage by verifying actual speaker system impedance prior to operation. Unlike conventional volt/ohm meters, which measure DC resistance, this unit utilizes an internal 1KHz oscillator to measure true impedance Features: Accurately measure speaker lines that utilize impedance matching volume controls, switchers,...

Electronic solders typically contain rosin-resin compounds and lead, which when heated may create noxious fumes. Prolonged exposure to these fumes is considered potentially harmful and may create health problems including headaches, nausea and eye irritation. The Tenma Solder Fume Extractor greatly reduces this hazard by effective removing these problem fumes from the air. Features: Highly efficient fan Activated carbon filter Fully adjustable stand ESD safe construction Unit includes one filter Replacement...
