Universal demonstration meter for pulse counting and rate, frequency, period and time measurements with serial interface for computer connection (incl. windows software)
High-performance ring-core isolating transformer which electrically isolates the consumer circuit from the power mains. Protection device for limiting the starting current. With analogue RMS meter for indicating the output voltage.
Continuously adjustable high-voltage source with 10-turn potentiometer and built-in digital display for output voltage; highly stabilized, for supplying the scintillation counter (559 901).
Floating high-voltage source with centre tap, continually adjustable or controllable via an external voltage, for electrostatic experiments, experiments on radioactivity, as well as operation of spectral tubes, gas discharge tubes and field-emission microscope. With built-in high-voltage proof transformer for tapping a heating voltage (6.3 V/2 A) for electron tubes. The integrated 2½ digit instrument permits…
High-voltage source, continually adjustable or controllable via an external voltage, for electrostatic experiments. The integrated three-digit display shows the voltage present at each of the output sockets. Passive current limiting ensures that no dangerous contact voltages can occur.
Current-limited to 2 mA, thus presenting no contact hazard. For generating a brief ignition spark or a constant spark gap with contact-safe high-voltage sockets and additional ground socket. Especially suitable for experiments on water synthesis.
For measurement of currents, charges (static) and voltages at low-error current levels in connection with an external voltmeter with an internal resistance exceeding 3 kΩ and a range between 0.3 V and 3 V (10 V max.), for example demonstration moving-coil instrument (531 900), and TY or XY plotters. Including BNC-4-mm cable (575 24). Examples…
For measurement and registration of DC voltages in the mV and µV range as well as voltage transients in the mVs and µVs range. With large front panel LED display. An analogue output carrying the amplified signal for connection to a measuring instrument or a recorder is provided. The unit is very insensitive to low…
Multipurpose AC/DC measurement amplifier with power output stage. Can also be used as precision power supply. With built-in bias voltage source which makes an external voltage supply unnecessary when. Virtually misoperation- proof due to shortcircuit proof output, thermal overload protection and LED indicators for voltage overdrive and exceeding the maximum output current. Examples of applications:…
