MP523

pH/ISE Meter

Features

Suitable for scientific research, biotechnology, pharmaceutical and food areas such as conventional high-precision pH measurements and ion concentration measurements (please choose the appropriate ion electrode according to need.)
 
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.
 
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.
