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.

Chapter 2 Meter Overview
A large bright LED display shows results in the main (middle) field.
Temperature is displayed in the upper field. The lower display shows
millivolts. The current operation mode is indicated along the right side of
the display. The buffers used during the last pH calibration are designated by
the indicators along the left side of the display. See Figure 2.

setup – Indicates that the meter is in the setup menu, which is used to
define or view meter operating parameters.
LogR – Indicates that the meter is in the LogR temperature measurement
or calibration mode. Automatic temperature compensation is activated
in the meter setup menu and achieved through the pH electrode. LogR
function is active when the LogR icon appears in the display.
ATC – Indicates that an ATC probe is connected to the meter and
operational. Manual temperature compensation is activated when the ATC
and LogR symbols are not displayed.
°C – The ATC icon in the upper display is lit when temperature
is measured with an ATC probe. The LogR icon is lit when LogR
temperature measurement is activated. If neither is on, manual temperature
setting is active.
ready – Displayed when the electrode signal has stabilized (pH, conc, rel
mV, mV and °C) and when the calibration standard input has stabilized.
The 320 meter has a six button keypad that is used to control all
meter functions.

Power Supply – All PerpHecT meters are designed to operate with a 110
V line adaptor, Cat. No. 020125, 220 V line adapter, Cat. No. 020130
or 240 V line adapter, Cat. No. 020135. Plug the line adaptor securely
into the line adapter input on the back of the meter and then plug the line
adapter into an appropriate wall outlet.
Electrode Input – Attach a PerpHecT pH electrode or other pH electrode
with a BNC connector to the BNC input on the back of the meter. Slide
the electrode connector onto the BNC input and then push in and turn the
connector clockwise to lock it into position. Electrodes with U.S. standard
connectors may be used with an adaptor, Cat. No. 090033. Connect
reference electrodes with pin tip connectors by pushing the connector
directly into reference input. See Figure 4.
ATC Probe – Attach an ATC probe to the ATC input on the back of the
meter by sliding the connector straight in until it is firmly in place. Use
only Thermo Scientific Orion ATC probes that are designed for PerpHecT
meters, Cat. No. 927005 (epoxy body), Cat. No. 927006 (glass body) or
Cat. No. 927007 (stainless steel body).
RS232 – Attach the RS232 connector to the RS232 input on the back of the
meter when using a printer or computer (350 and 370 meters only).
