WPI FD223a Dual Channel Differential Electrometer

Dual differential, high impedance amplifier/electrometer

World Precision Instruments

The FD223a electrometer was designed specifically for use with intracellular ion selective electrodes fabricated using glass micropipettes and liquid ion exchangers.

Features:

  • Dual channel with very high input impedance
  • Separate outputs for Channel A, B and A-B (Differential)
  • Independent DC offset controls
  • Test port
  • Standby mode

The active head stages allow the researcher to locate the probes directly at the measurement site to minimize noise that would normally be picked up by longer cable runs. Driven guard shields cover the micropipette holders to further reduce the potential for interference from external sources of electromagnetic noise.

The FD223a is equipped with a test resistance port which is used to measure and adjust each probe for minimum leakage current. Each channel has a standby mode which clamps the head stage input voltage to zero, preventing extreme saturation or possible damage to the high impedance input amplifier.
