Chapter 1

Introduction

Thermo Scientific Orion pH and ISE meters are designed for every

application, from basic pH measurements to advanced concentration analysis

using ion selective electrodes . This user guide contains information on the

preparation, operation and maintenance for the 320, 350 and 370 PerpHecT

LogR meters . The 320 meter measures pH, millivolts (mV) and temperature .

The 350 meter measures pH, millivolts (mV), oxidation-reduction potential

(ORP) and temperature . The 370 meter measures pH, concentration (ISE),

millivolts (mV), oxidation-reduction potential (ORP) and temperature .

All PerpHecT meters feature patented digital LogR technology, which allows

fully temperature compensated measurements without a separate ATC probe .

For maximum system accuracy, use Thermo Scientific Orion PerpHecT

and PerpHecT ROSS pH electrodes . PerpHecT meters are microprocessor-

controlled and feature pH autocalibration, patented digital LogR pH

measurement mode, sealed keypads and large easy-to-read LED displays .

PerpHecT meters are ideal for busy, multi-user laboratories or plant

environments . The pH measurements are easy with the help of advanced

features such as autocalibration, LogR mode, automatic temperature

compensation, choice of pH resolution and diagnostic operator assistance

codes .

• The 320 PerpHecT meter is a basic meter designed for routine pH and

mV measurements .

• The 350 PerpHecT meter offers an RS232 interface for connecting the

meter to a printer or a computer . Other features include GLPcheck for

monitoring electrode performance and GLPdoc that creates printouts

that are compatible with good laboratory practice (GLP) requirements .

• The 370 PerpHecT meter offers basic ISE functions for measuring ion

concentrations using an ion selective electrode and an RS232 interface for

connecting the meter to a printer or a computer . Other features include

GLPcheck for monitoring electrode performance and GLPdoc that

creates printouts that are compatible with good laboratory practice (GLP)

requirements .
