HP-200-K (Four-Wire Analyzer)

HP-200-K (Four-Wire Analyzer)

Industrial pH meter

One-touch calibration function Realizes gentle measurement by combination with lead-free ORP electrode

Division: Process Water
Manufacturing Company: HORIBA Advanced Techno Co., Ltd.

 

  • Improved single-touch calibration for greater ease of use
  • Calibration history display
  • Extensive interfaces (2-channel transmission output, RS-485 compatible, 6-relay output)
  • Control output (upper and lower limits ON/OFF and duty control in a shared time and a zone)
  • New pH electrode lineup
