HD-300

HD-300 (Two-Wire Transmitter)

Industrial dissolved oxygen analyzer (Two-Wire Transmitter)

Realizes both the cartridge method membrane replacement and the membrane internal liquid replacement regeneration system Responds to a wide range of measurements(boiler water/rivers/aeration treatment, etc.)

 

Division: Process Water
Manufacturing Company: HORIBA Advanced Techno Co., Ltd.
  • Membrane type polarography method
  • Span calibration by air preceded by auto-zeroing (Electrical auto zeroing function)
  • Self-diagnosis of membrane damage and infiltration into the probe
  • On-site membrane replacement as well as whole sensor replacement
