1. INTRODUCTION
Thank you for purchasing our Con 700 series benchtop meter.
This microprocessor-based meter is economical and simple to
use. The design incorporates a large LCD for clear viewing, yet
offers a small footprint to conserve space.
The CON 700 measures conductivity or TDS, and temperature
(ºC or ºF) simultaneously.
Each meter includes a convenient slide-out card for quick
reference.
Some configurations include an electrode arm and metal
bracket which can be easily attached to the left or right side of
the meter according to your preference.
The CON 700 series benchtop meter replaces our popular CON
510 series meter that was introduced in 2002.
We take great pride in every instrument we manufacture
and hope this one serves you well.

2. GETTING STARTED
2.1 Keypad Functions
Powers the meter on and off. Upon power on, the meter
automatically begins in the mode that was last used.
Calibration and memory values are retained even if meter
is unplugged.
Toggle between available measurement modes—
Conductivity with Temperature or TDS with Temperature.
Also used to switch to Temperature calibration during
Conductivity or TDS calibration mode.
Press and hold for 5 seconds to enter SETUP mode.
Toggles between measurement and calibration modes.
In SETUP mode, returns user to the measurement mode.
Confirms calibration values in CAL mode.
Confirms selections in SETUP mode.
Changes range and resolution in MEAS mode.
View recalled values in memory mode.
MI (Memory Insert) stores values into memory.
Increase value. Scroll up in SETUP & CAL modes.
MR (Memory Recall) recalls values from memory
Decrease value. Scroll down in SETUP & CAL modes.
Freezes measured reading. Press again to resume
live reading.

3. ELECTRODE INFORMATION
The CON700 includes an electrode with a nominal cell constant of
k = 1.0, built-in temperature sensor, and 1 meter cable. The Ultem
body housing has good chemical resistant properties. The
electrode design offers fast temperature response and reduces air
entrapment, ensuring accurate, repeatable, and stable readings.
he wetted materials of the probe include:
T
Polyetherimide (Ultem) – protective probe guard
Polybutylterphalate (Valox) – sensor housing
Stainless Steel (SS 304) – 2 bands
The protective probe guard can be removed temporarily for
cleaning however it must be re-attached during measurement and
calibration. Erroneous results will occur while the probe guard
is removed.
Always immerse the probe beyond upper steel band for best
results. Use the fill line on the outside of the probe guard for
reference.
4. CALIBRATION
4.1 Automatic or Manual Calibration
The CON 700 is capable of automatic or manual calibration for
conductivity, and manual calibration for TDS.
In the automatic calibration mode, the meter will automatically select
one of (4) conductivity calibration standard values depending o
range and normalization temperature being used (TABLE 1).
If you only use calibration standards that are listed in TABLE 1,
automatic calibration is recommended. If you intend to calibrate with
one or more standards that are not listed in
must be set for manual calibration instead.
