Page 5: 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 6: 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. -

Page 8: Electrode Information
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. -
Page 9: 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 10: General Calibration Tips
The factory default is Single-Point Calibration. See Section 6.11 to change this setting. 4.3 General Calibration Tips For best results, periodic calibration with known accurate standards is recommended. A maximum of one calibration point per range can be performed. If multiple calibration points are used in the same range, the most recent one will replace the previous one. -
Page 11: Manual Conductivity & Tds Calibration Procedure
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. -
Page 12: Automatic And Manual Ranging
Dip the probe into the sample beyond the upper steel band (utilize the fill line on the outside of the probe guard for reference). Allow time for the reading to stabilize. Note the reading on the display. The clear yellow protective probe guard must be attached during measurement. -

Press to choose READY “On”, READY “OFF”, or Auto HOLd. Press to confirm. 6.5 P3.2 ºC ºF (Celcius Or Fahrenheit) Press Press to select ºC or ºF. Press to confirm. 6.6 P3.3 AtC (Automatic Temperature Compensation) Press Press to select “Yes” or “No”. Press to confirm. -
Page 15: P3.6 T.nr (Normalization Temperature In ºc)
See Section 8 – Calculating Temperature Coefficients. Press Press to select the desired value (0.00 to 10.0). Press to confirm. 6.9 P3.6 t.nr (Normalization Temperature in ºC) When Automatic Temperature Compensation is used, measurements are adjusted by the temperature coefficient to the normalization temperature. -
Page 16: Cell (Nominal Cell Constant)
6.12 P3.9 CELL (Nominal Cell Constant) The CON 700 includes a probe with a nominal cell constant (k) of 1.0. Use probes with k = 0.1 and 10 (sold separately) for improved performance in extreme sample ranges. Use this setup function to change the cell constant if necessary. -
Page 17: 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 18: 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. -
