Precision pH/Conductivity Meter

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.
