Chapter I
General Information
Introduction
Orion provides pH and ISE meters for every application from basic pH
measurements to advanced Ion Selective Electrode work. This manual
describes the operation and use of the Orion PerpHecT™meter line. The
PerpHecT meters consist of the following meters: the Orion 310 pH/
Temperature Meter, the Orion 320 pH/mV/ORP/Temperature Meter, and
the Orion 330 pH/mV/ORP/Temperature Meter.
All PerpHecT meters feature the Orion patented digital LogR™technology
which allows fully temperature compensated measurements without the
need for a separate ATC probe.

2General Information
All meters are microprocessor-controlled and feature pH autocalibration,
patented digital LogR pH measurement mode, sealed keypads and large
easy-to-read LED displays.
These systems are ideal for busy, multi-user laboratories or plant
environments. 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 Orion 310 is a basic pH Meter which comes complete with a
PerpHecT combination glass pH temperature electrode. The choice of
a PerpHecT Ag/AgCl electrode (Orion 9202BN) or PerpHecT ROSS™
electrode (Orion 8202BN) is available.
The Orion 320 is a pH/mV/ORP/Temperature Meter which comes
complete with a PerpHecT combination glass electrode. The choice of
a PerpHecT Ag/AgCl electrode (Orion 9202BN) or PerpHecT ROSS
electrode (Orion 8202BN) is available.
The Orion 330 is a pH/mV/ORP/Temperature Meter with RS232
interface for connections to a printer or a computer. It comes complete
with a PerpHecT combination glass electrode. The choice of a PerpHecT
Ag/AgCl electrode (Orion 9202BN) or PerpHecT ROSS electrode (Orion
8202BN) is available.

Meter Description
A. Display
Orion 310
A large bright LED display shows pH results and temperature in the main
field. The current operation mode is indicated along the right side of the
display. “Ready” is designated by the indicator along the left side of the
display. See Figure 2.
Orion 320 and 330
A large bright LED display shows results in the main field. Temperature
is displayed in the upper field. 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.

SET UP (Orion 320 and 330)
Indicates that the meter is in the setup mode which is used to define or
view operating parameters.
LogR
Indicates that the meter is in the LogR temperature measurement or
calibration mode. LogR is activated in the setup mode (or with the temp
key Orion 310) and measured with the pH electrode. LogR function is
activated when the LogR icon appears in the upper display.
ATC
Indicates that an ATC probe is connected and operational. Manual
Temperature Compensation is activated when the ATC and LogR symbol
are not displayed.
READY
Displayed when the electrode signal has stabilized. Also displayed
when calibration standard input (pH and Temp) has stabilized.
° 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. For the Orion 310, temperature is displayed by pressing
MODE key.
