  • Page 4: Introduction

    INTRODUCTION Congratulations on your purchase of the EC/TDS/SAL (Electro Conductivity/Total Dissolved Solids/Salinity) TRACER PockeTester. The TRACER is a revolutionary, first of its kind measurement device that offers direct reading of conductivity, TDS and salinity with one electrode. Careful use and maintenance will provide years of reliable service.

  • Page 7: Basic Operation Powering The Tracer

    BASIC OPERATION Powering the TRACER The Tracer uses four CR2032 Lithium Ion batteries. If the batteries are weak, the BAT indicator will appear on the display. Press the ON/OFF key to turn the TRACER on or off. The auto power off feature will shut the TRACER off automatically after 10 minutes after the last button push.

  • Page 8: Changing The Displayed Tempreature Units

    Changing the Displayed Temperature Units To change the displayed temperature units between °F or °C: 1. With the TRACER off, press and hold the CAL/RECALL button. 2. With the CAL/RECALL button pressed, momentarily press the ON/OFF button. When SELF CAL appears in the display, release the CAL/RECALL button.

  • Page 9: Testing Getting Started

    TESTING Getting Started 1. Remove the cap from the bottom of the TRACER to expose the electrode. 2. Before the first use, rinse the electrode in deionized water and dry. 3. For best results, calibrate for conductivity with a standard in the expected range of the sample.

  • Page 10: Measurement

    Measurement 1. Fill a sample cup to the 20 mL line with the test sample. Sample depth must be greater than or equal to 1.5 inches. 2. Immerse the TRACER electrode in the sample. Make sure the electrode is completely submersed. 3.

  • Page 11: Storing Readings

    7. Press the ON/OFF button to turn the TRACER on. Make sure the meter is in the TDS mode. 8. Immerse the electrode in the filtrate. Make sure the tip of the electrode is completely immersed. 9. Stir the filtrate with the electrode to create a homogeneous solution. 10.

  • Page 12: Calibration

    Clearing the Stored Memory Turn the TRACER on. Press and hold the ON/OFF button for 4 second the display will briefly desplay “clr” when the memory is cleared. CALIBRATION For the most accurate results, allow sufficient time for the temperature of the probe to reach the temperature of the sample before calibrating.
  • Page 13 NOTE: Each time the calibration mode is entered all calibration range indicators will be cleared, but only the calibration data for the currently selected range will be replaced. The calibrations for the other two ranges will be saved even though the indicators for those ranges are no longer displayed.

  • Page 16: Maintenance Storage

    MAINTENANCE Storage 1. Rinse the electrode in distilled or deionized water. 2. Store the electrode dry with the cap on. 3. Always rinse the electrode in deionized water between measurements to avoid cross contamination. Double rinsing is recommended when high accuracy is required. Battery Replacement 1.
  • Page 17 Electrode Cleaning Recommendations Do not soak the electrode in the solutions for longer than the recommended length of time. To do so may cause a reference potential shift which will cause a degradation in performance or failure. When cleaning the probe, do not scratch or damage the platinized electrode surfaces.
