MP512 precision pH meter

●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.

● 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.
● Meter has the only product serial number.
● Dustproof and waterproof meter meets IP54 standards. All sockets are seal protected by the silica gel caps.
