Page 4: Introduction
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. -
Page 5: Getting Started
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. -

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 n the range and normalization temperature being used (TABLE 1). -
Page 8: Single Or Multi-Point Calibration
The factory default is automatic conductivity calibration. See Section 6.10 to change this setting. There is no automatic calibration value available for conductivity range 1. TABLE 1 Automatic Calibration Values Range Conductivity Normalization Temperature Range 25 ºC 20 ºC 0.00 – 20.00 μS None None 20.1 –... -
Page 9: General Calibration Tips
Rinse or immerse the probe before calibration and between samples with clean water (deionized water is ideal). The CON 700 has non-volatile memory which will retain all calibration values, as well as meter settings and memory values upon meter shut down or unexpected power loss. -

4.5 Manual Conductivity & TDS Calibration Procedure Press as needed to select conductivity (μS or mS) or TDS (ppm or ppt) calibration. Dip the electrode into the calibration standard and press Provide stirring for best results. The primary display will show the current reading, while the secondary display will be the factory default value. -

Meter defau lt is 1.0 to match the included probe. k = 0.1 ideal for low measurements <20 µS (<10 ppm). k = 1.0 ideal for mid-range measurements k = 10 ideal for high measurements >20 mS (>10 ppt). -
Page 16: Calculating Tds Conversion Factor
CALCULATING TDS CONVERSION FACTOR You can calibrate TDS using the value of the calibration standard solution at a standard temperature such as 25 ºC. To determine the conductivity- to-TDS conversion factor use the following formula: Factor = Actual TDS ÷ Actual Conductivity @ 25 ºC ... -
Page 17: Calculating Temperature Coefficients
CALCULATING TEMPERATURE COEFFICIENTS To determine the temperature coefficient of your sample solution use this formula: Where: tc = Temperature coefficient 25 = 25 ºC = Conductivity at Temp 1 = Conductivity at Temp 2 T1 = Temp 1 T2 = Temp 2 NOTE: A controlled temperature water bath is ideal for this procedure. -
