The calibration standard..for these instruments and <br /> their suppliers are listed in Table 4-1. The electric well sounder will be calibrated with <br /> f u a steel tare before it enters the field. <br /> i <br /> s- Table 4-1 <br /> s Calibration Standards and Suppliers , <br /> #, Instrument Calibration Standard Supplier ; <br /> pH meter pi-14, 6.8, 10 buffers Fischer Scientific <br /> Conductivity meter EC 225, .1,000 µml:oslcm Tustin, CA <br /> HNu Benzene, 55 ppm HNu Systems, Inc. <br /> ` f Newton Highlands, MA <br /> t i The-results of calibrations and repair records will b: recorded in a field notebook. _ <br /> Scheduled periodic calibration of testing equipment does not relieve field personnel of <br /> the responsibility of employing properly functioning equipment.
