pH/DO Meter

pH/DO Meter
ELE-525

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.

  • Equips new type of DO electrode which has function      of automatic temperature compensation and automatic salinity compensation      as well as automatic air pressure compensation inside meter to make DO      measuring mode has temperature, air pressure and salinity automatic      compensation, easy to use, accurate to measure.

  • Polarogram type DO electrode has special electrode      calibration cap. Only needs 3 to 5 minutes for electrode polarization.      Electrode adopts combination diaphragm cap which very convenient to use.      Each DO electrode equips with three spare diaphragms caps.

  • Meter has the only product serial number.

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