Kennedy/Jenks Consultants <br /> SOG 6: Standard Operating Guideline <br /> Field Measurement of Temperature and <br /> Specific Conductance <br /> 6.1 Introduction <br /> This guideline provides procedures for measuring specific conductance and temperature using a <br /> Yellow Springs Instruments (YSI) conductivity meter. <br /> 6.2 Equipment <br /> ` YSI conductivity meter <br /> • Standard conductivity solutions (1,000; 10,000 and 100,000 µmho/cm) <br /> • Deionized water in squirt bottle <br /> Pint plastic jar <br /> • Small brush <br /> 6.3 Field Procedures <br /> This guideline describes the procedures that will typically be used by Kennedy/Jenks Consultants <br /> personnel during performance of field temperature and specific conductance measurements. <br /> 1. Check red line and zero point on meter. Adjust meter needle to read zero in the off position <br /> �. using adjustment screw below needle. Adjust meter to red line in the red line position using the <br /> red-line knob. Replace batteries if meter will not adjust to the red line. <br /> 2. Rinse sample cup (500 ml plastic) beaker with sample water three times. <br /> 3. Fill sample cup with water sample. <br /> 4. Rinse conductivity probe with deionized water then with sample water and place probe in <br /> sample cup. <br /> 5. Submerge conductivity probe in sample so that flow cell holes are immersed. Pump probe up <br /> and down a few times to dislodge bubbles. Do not submerge to bottom, for this causes false <br /> high readings. Tum instrument on to highest scale multiplier and downscale to appropriate scale <br /> for sample reading. Multiply reading on scale by the correct multiplier from the dial and record to <br /> the nearest half-increment between marks. Turn function knob to the Temp position. Read <br /> sample temperature to the nearest 0.5 degrees C after temperature has equilibrated (about one <br /> minute). <br /> 6. Remove probe from sample and rinse with deionized water(soak). <br /> 7. Report conductivity and temperature so temperature correction can be applied if necessary. <br /> fr <br /> Groundwater Protection Work Plan, The Wine Group SOG 6 <br /> Franzia Winery, Ripon, California 1 <br /> gtisymuplatlminy'o6103103017001_ruregra,p109reportsixakplanbppmCiceMlBrompspeaon0.dac <br />
