precision pH meter

Introduction

High precision laboratory bench pH meter, which is suitable for measuring solution of weak ionic strength, and the turbid liquid or colloidal solution. It can be used in the high-precision pH measurements, such as scientific research, quality control, biotechnology, fine chemicals, acid-base titration, etc.

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.

Meter has the only product serial number.

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