USE TABLE

Find the "TR7" result in the table below to determine the Phosphate concentration in ppm (parts per
million). (Example: a "TR7" result of 85.3 (use only the 85 for the chart) equals a Phosphate value of
0.39 ppm). Record result. After testing is completed, rinse cell immediately.
Iron results require the table below. Follow eXact
