Product Description

Item: PH/mV/ISE/Conductivity/DO Meter with low voltage display
Model: ELE-523

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.
· 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.
