INTRODUCTION
Sper Scientic is pleased to o󰀨er the following line of bench-top meters:
Model 860031 (pH/mV)
Model 860032 (Conductivity/TDS/Salinity)
Model 860033 (Water Quality)
Please note that the meter itself is identical in each of the above models.
Each model can be used for pH/mV, Conductivity/TDS/Salinity or Water
Quality depending on the probe used.
To utilize your meter under additional parameters, please refer to the list
of probes in OPTIONAL ACCESSORIES on page 51.
Instructions for all three models are contained within this manual. Refer
to the TABLE OF CONTENTS for the subsection within MEASUREMENT
PROCEDURES that corresponds to the particular parameter you are
measuring.
FEATURES
• Multi-display LCD screen
• N.I.S.T. bu󰀨er recognition
• Hold function
• Maximum and minimum
• Reliable, replaceable probe with temperature compensation
• Easy to view probe calibration data
• “Ready” icon on LCD display indicates stability for reading
• PC connection for online logging and uploading 99 memories for analysis
• Automatic or manual temperature compensation
• Analog output for chart recorders

POWER SUPPLY
The meter is powered by a 9 Volt DC adapter (included). The plug of the
adaptor is USA type; you will need to purchase a plug converter if using
the meter outside of the US.
Plug the adaptor into the power port labeled “DC,” located on the rear of
the meter.
METER COMPONENTS
Meter Drawer
A built-in drawer is located on the bottom of the bench-top meter. Pull the
drawer out and use to store notes and other important reference data.

METER COMPONENTS
Probe Holder
The probe holder is composed of two parts: the base and arm. Holder
assembly does not require tools. The maximum swing angle is 70° and
the maximum height of the holder is 378 mm.
Holder Assembly
Holder Disassembly
1. Turn the base upside down.
2. Use a cylindrical object with an approximate 12 mm diameter to push
the arm out of the base.
To disassemble the holder from the base:

METER COMPONENTS
Attaching Holder to the Meter
After assembling the holder, attach the holder to the meter.
1. Find the two holes on the bottom of the meter that are used to hold
the base.
2. The holder can be attached to the right or left side of the meter
Locate the two holes at the
bottom of the meter.
The cylindrical knob
on the holder base is
designed to t into the
hole on the bottom of
the meter.
The holder can hold up to 4
probes. The wire of the probe
can be xed to the arm.
Turn clockwise to lock the holder
into place. Turn counterclockwise
to adjust the holder up and down.

LCD DISPLAY
Primary Data Screen displays pH, mV, ORP, Conductivity, TDS or
Salinity value.
Icons CON, TDS, SALT, ORP, pH, mV indicate the parameter displayed.
Icons ppt, ppm, mg/l, mS, µS, kPA, or mmHg indicate the unit of
measure displayed.
READY indicates the reading is stable.
AUTO indicates auto-ranging function.
MAX, MIN indicate a maximum or minimum memory value.
HLD Holds the current reading on the display.
REC indicates the meter is in recall mode.
MEM indicates the current measured value is saved.
The digital number under MEM indicates the total number of saved records.
The are real time Y-M-D (Year-Month-Date) or H:M:S (Hour-
Minute-Second).
ATC indicates the meter is in Automatic Temperature Compensation Mode.
The temperature display is indicated at the bottom of the LCD.
Temperature unit °C or °F is selectable.

KEYPAD
POWER/SET Press to turn the meter on/o󰀨. Press and
hold for more than 1 second to enter SET
Mode. The meter will default to the last mode
used when turned o󰀨 and back on.
CAL/ESC Switch between NORMAL and
CALIBRATION Mode. Press to enter
manual temperature setting. In Calibration,
Setting or Recall Modes, press to return to
Normal Mode.
HLD/REC Press to freeze the reading. Press again to
release. Press for more than 1 second to
switch between NORMAL and
RECALL Modes.
MODE/▲ Press to switch the mode.
Press to increase the setting value.
MEMO/▼ Press to save the current reading.
Press to decrease the setting value.
MN/MX/
CONFIRM
Press to conrm calibration or parameter
setting. Press to view the min/max of the
memory in Recall Mode. Press to select
AUTO or Manual ranging when in
Cond./TDS/SALT.

REAR PANEL
The bench-top meter provides a complete set of input connectors for
various commonly-used accessories:
Connection Function
DC Connection of the AC to DC adaptor power supply
RS232 Connection of a RS232 or USB cable to a computer
to capture online or stored data
MIC Conductivity probe input
GND (I) Earth ground jack inputs (standard tip connectors)
GND (II) Earth ground jack inputs (standard tip connectors)
ANALOG Strip chart recorders input.
Use subminiature plug with positive tip.
BNC The port accepts pH, ORP with a BNC connector.
Ensure that the connector is clean and dry before
connecting.
ATC Phone jack input for the temperature probe for
automatic temperature compensation
