4000 DC Degas Conductivity Analyzer

4000 DC Degas Conductivity Analyzer

Fast and accurate degassed conductivity monitoring with Waltron’s compact and innovative 4000 DC


The Waltron 4000 DC Degas Conductivity Analyzer utilizes innovative, dynamic degassing technology for precise conductivity measurements in ultra-pure water systems. Engineered for reliability and ease of use, it seamlessly integrates after cation exchangers. Supported by Waltron’s strong U.S. team, the 4000 DC ensures accurate, continuous monitoring with unmatched performance.


  • Revolutionary heatless degassing technology
  • Achieves 93.5% degassing efficiency in less than 90 sec
  • Sample temperature fluctuation does not affect accuracy
  • No gas emissions or volatile acids
  • Significantly reduced turbine start-up times
  • Surface mount can be easily linked to a Waltron 9095 or 4095 Multicon
  • Bright 3.5″ TFT color display shows precise values from specific and cation conductivity sensors, and generates a calculated pH value for the same sample point
  • Easy to install and configure with alarms, relays, and two 4-20mA outputs per channel
  • On-board data logging and live trending
  • Choice of 24VDC or 110-240VAC versions
