Two-channel amplifi er for electro-physiological experiments. The ampli fi ed signals from both channels can be displayed on a storage oscilloscope or with the help of the Bio-measurement interface connected to a computer. Gain and frequency response are dependent on the selected experiment: action and muscle potentials in live earthworms (Worm), electro-retinograms (ERG), electrocardiograms (ECG), electromyograms (EMG).

Measuring ranges: max. ±1 mV (worm), max. ±10 mV (ECG, EMG, ERG)
Frequency ranges: 120 – 1800 Hz (worm) 0.5 – 1800 Hz (ERG, EMG) 0.5 – 30 Hz (ECG)
Power supply: 5 V DC / 100 mA via plug-in power supply or bio-measurement interface (P-1020602)
Connector for bio-measurement interface: Sub-D socket, 15-pin
Connector for oscilloscope: BNC socket
Connector for measurement chamber: 3.5-mm jack socket
Dimensions: approx. 175x105x30 mm3
Weight: approx. 335 g
