Nitrate concentration meter

Nitrate concentration meter
ELE-523-11

Introduction:

  • Meter meets with the requirement of international      GLP standards. Its features up to automatic calibration, automatic      temperature compensation, data storage, timing measurement, clock display,      RS-232 output, function setting and self-diagnose etc.

  • Nitrate electrode range: 1 ~ 5 pNO3 (10-1 ~      10-5 mol / L).

  • Configuration electrode: nitrate ion electrode,      reference electrode, temperature electrode and three-in-one combination pH      electrode.

  • Configuration solution: nitrate ion standard      solution, ionic strength regulator, reference electrode solution and pH      correction solution.

  • There are three different measurement modes: stable      display mode; time measurement mode; continuous measurement mode.

  • Automatically recognize 13 kinds of pH buffer      solution. User can choose anyone from four series of standard buffer      solutions: Europe & USA series, NIST series, CHINA series and      Self-defined series

  • High purified water and ammonia added purified water      pH measuring mode can be set up, especially suitable for electric power      and petrochemical industry

  • With EH redox potential measuring mode can directly      display ORP value which against standard potential of hydrogen electrode.

  • There are 10 kinds of common ions can be selected in      the ion concentration measuring mode, user also can self-define other      ions.

  • Can switch 4 kinds of concentration unit: pX, mol/L,      mg/L and ppm.

  • Meter has the only product serial number.

  • Dustproof and waterproof meter meets IP54 standards.      All sockets are seal protected by the silica gel caps.
