Secadora de Roupas 10Kg Latina, Branco, SR555, 4 Cabides, 110V

sr555The SR555 and SR556 are ideal low‐noise current preamplifiers for SRS’ lock‐in amplifiers, and can also be used for any other small current detection purposes.Current amplifiers provide gain close to the experimental detector, allowing the user to minimize input cable length and its corresponding input capacitance. The SR555 minimizes noise and pickup before they permanently degrade
