Lab pH/Conductivity Meter

Lab pH/Conductivity Meter
Model: ELE-521

Introduction:

  • The most widely used pH + Conductivity      Double-Parameter measurement 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 pH buffer solution. User can      choose anyone from three series of standard buffer solutions: Europe &      USA series, NIST 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.

  • Can switch Conductivity, TDS, Salinity and      Resistivity.

  • Meter has the only product serial number.

  • Dustproof and waterproof meter meets IP54 standards.      All sockets are seal protected by the silica gel caps.
