Измерительный усилитель (230 В, 50/60 Гц)

Описание товара

For the measurement of extremely small currents, voltages and charges in electrostatics and atomic physics. A voltage signal proportional to the measurement variable is available and can be supplied to a voltmeter as a display instrument. Over voltage protection up to 300 V provided by a high-voltage-proof input. Includes a built-in fixed voltage output for external circuit connections (e.g. measurement bridges). Measurement ranges (with respect to 1 V output voltage): Voltage: 0.1 mV up to 100 V (7 ranges) Current: 10-11 A up to 10-5 A (7 ranges) Charge: 10-11 As up to 10-7 As (5 ranges) Input impedance: Voltage: 10 MΩ Current/charge: 0 Ω, voltage-proof up to 300 V Measurement accuracy: 3 % Analogue output: 0 up to 10 V, adjustable zero point, reversible polarity Fixed voltage output: + 15 V, max. 50 mA Dimensions: 235x230x180 mm Weight: ca. 2.8 kg
