DY2000 Series Multichannel Potentiostat


  • Sensitive
  • Easy to Use
  • Low Noise
  • Low Cost
  • Max. Current: ±2 mA
  • Min. Current: 76 fA
  • Potential Range: ±2.000 V
  • Max. Sampling Rate: 10 kHz (16-bit)

  • Cell Configuration: (CE1, RE, WE1), (CE2, WE2)
  • Tech: (iT, CV, LSV, DPV, NPV, MSP, SWV, ...)
  • Cell On/Off Control, Ext Trigger, Analog Output

The DY2000 series integrates either a one or two channel potentiostat into a single compact design. Each channel has a low-noise analog current-to-voltage pre-amplifier with seven selectable gain stages, analog filters, a high impedance voltage amplifier and a 16-bit bias DAC. A 16-bit, 200 kHz ADC is used for data acquisition.

The unique hardware design makes the DY2000 suitable for applications such as the detection of extremely low electrical currents, and the study of electrochemical phenomena using microelectrodes.

DY1000 Sweep DDS Lock-In Amplifier


  • Digital Accuracy
  • Multi-Function
  • Portable
  • Easy to Use
  • Max. Freq.: 10 kHz (DDS)
  • Min. Freq.: 0.008 Hz
  • Amplitude Range: ±10.00 V
  • Harmonic Lock-In: 1.0f to 100.0f

  • Auto Freq. Sweep
  • 3-Omega Method
  • Synchronized Dual Function Generators
  • Non Integral Harmonic Lock-In

Lock-in amplifiers are widely used in physics, chemistry, biology, and many other fields to detect very weak signals in the presence of a noisy background. However, in many cases, such usefulness could be limited by the complicated operation of conventional lock-in amplifiers. The DY1000 Sweep DDS Lock-In Amplifier introduces a new and convenient way to operate lock-in amplifiers. The built-in frequency sweep function lets the DY1000 automatically experiment data for a user-defined frequency range and resolution. The frequency can be swept up or down in either linear or logarithmic modes. The amplitude and phase responses of an external system are measured simultaneously.
