Detailed Product Description

Introduction

● 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.

●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.
