Description

“MARK 903” flow is designed to measure the activity of hydrogen ions (pH), EMF and temperature of aqueous media. Operational control of the parameters of water-chemical regimes at thermal and nuclear power facilities.

Features of МАРК-903

  • the possibility of carrying out both laboratory and “field” measurements;
  • accurate and convenient measurements;
  • degree of protection IP 65;
  • МАРК 903 is airtight and has a protective casing, which provides dust and moisture protection;
  • self-diagnosis and easy settings;
  • temperature compensation is automatic;
  • there is an electronic notepad without dependence on food;
  • buffer solutions are recognized automatically;
  • included USB port and software;
  • the ability for the user to create folders and record up to 500 measurement groups;
  • illuminated graphic indicator;
  • the ability to create a data archive on a PC and manage it;
  • measurements are displayed in a convenient format;
  • low energy consumption;
  • continuous operation from AA batteries up to 600 hours.

МАРК-903 (flow-through) pH-meter warranty is 24 months (for the electrode system – manufacturer’s warranty).
