PHYWE Electrometer amplifier
Article No: 13621-00
Operational amplifier with high resistance input for quasi-static voltage measurement respectively charge measurement, in fail-safe-plastic housing. Suited for experiments with electrostatics e.g. charge measurement, capacity measurement of sphere-capacitor, measurement of direct voltages, quasistatic measurements and measurement of small currents. Power supply via 4 mm sockets or wall power supply with hole socket. Gain/amplification: 1.0 Input resistance: > 10000 GOhm Input current: < 0.5 pA Input capacitance: < 50 pF Input voltage: Amplifier (socket 1): ± 10 V- Second input (socket 2): 1 kV Power supply: 12 V AC/25 mA hole socket: 2.1/5.5 mm or External power source: 12 V AC, 25 mA 4 mm sockets Output voltage: ± 10 V Output current: 1 mA Output resistance: < 500 Ohm Operation temperature: 5...40°C Relative humidity: < 80% Dimensions: 65 × 113 × 35 mm Weight: 150 g
