Precision pH/Conductivity Meter
Model: ELE-522
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.
Automatically recognize 8 kinds of conductivity standard solution. User can choose anyone from two series of solutions: Europe & USA series and China series.
Adopt advanced and original conductivity measurement technology, use 1 pc of conductivity electrode (K=1), it can meet measuring accuracy requirement for range within 0.5μS/cm ~ 200mS/cm by using only one-point calibration.
Automatically select conductivity measurement range, when measuring high pure water, equipment automatically enter into temperature compensation of nonlinear model, especially for electricity, microelectronics and the pharmaceutical industry requirements.
Meter has the only product serial number.
Dustproof and waterproof meter meets IP54 standards. All sockets are seal protected by the silica gel caps.
