  • INQUIRY

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.
