Model 1900 Polarographic Amplifier
A-M Systems


The Model 1900 Polarographic Amplifier is specifically designed for low noise, precise amperometric measurements. The features of this research instrument easily permit the use of a wide range of commercial or custom polarographic oxygen or hydrogen sensors.

  • Low noise
  • Can use both Hydrogen and Oxygen sensors
  • Wide response range
  • Excellent resolution
  • Full scale digital panel meter displays current, mm Hg, x10, %, and %x10 outputs
  • Internal/external gateable electrode polarization
  • Single-ended or differential measurement
