Thermo Scientific Orion 320, 350 and 370 PerpHecT®LogR®Meter User Guide 1-1
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.
