Fluke 8506A40Hz to 20kHz, Digital MultimeterThe Fluke 8506A is one of our used Digital Multimeters with a bandwidth of 40Hz to 20kHz.The Fluke 8506A Digital Multimeter uses a fast thermal rms sensing technique for measuring ac which very significantly advances the state-of-the-art for ac measurements using a system DMM. It is several times more accurate than the calculating type of true-rms converter and is unmatched by any other DMM.Basic ac accuracy uncertainty is reduced to 120 parts per million, 24 hours for frequencies from 40Hz to 20kHz.
