9135 pH Analyser
Drinking and waste water
   Industrial process control : chemical, petrochemical, pulp and paper, food and beverage, sugar, steel, surface treatment industries
  Pure and ultrapure water analysis : steam generation and electricity production, semiconductors , pharmaceuticals industries

Features Applications
  • Universal transmitter (2 high impedance inputs) : accepts combined and simple pH electrode, reference electrodes, antimony electrodes, ORP (redox) electrodes.
  • Specific temperature compensation capabilities :
          - following Nernst equation
          - user–programmable coefficient
          - non–linear for ultrapure water
          - non–linear for process water
  • Auto diagnostic of the measurement loop :  checking of pH and reference electrode impedance.
  • Several communication outputs available : 2 analog outputs, 4 relays, RS485 serial bus
  • Integrated controller : frequency or pulse modes, bi-directional proportional function
  • Large choice of calibration methods :
        - automatic determination of buffer solutions values
        - manual set-up of process pH values, offset and slope specifications of the electrodes
