Chloride (as NaCl) Test Procedure
TR7
TURN METER ON
1
Press the ZERO/ON button to power the meter on; the display will show all annunciators,
then the current MENU selection, followed by the last reading.
SELECT TEST: TR7
2
Press and re-press the MENU button until the display shows the parameter TR7.
PREPARE THE CELL
3
Using deionized or distilled water, rinse the cell at least 3 times to minimize potential cross
contamination from a previous test. Finally, fill the cell to the top with deionized or distilled water.
ADD THE SAMPLE
4
Use the small pipet provided to add 0.1ml of the sample to the water in the cell.
ZERO METER
5
Press the ZERO/ON button. The cursor will move across the display, followed by 100 %T.
Sample is ready for testing.
DIP STRIP
6
Dip the eXact
®
Strip Micro CHLORIDE (as NaCl), Part No. 481657 into the CELL and
immediately press READ. This starts the 20 SECOND countdown timer. During this time move
the strip in a gentle back and forth motion. Remove and discard the strip when the time
displays 1. The cursor will move across the display, informing you that it is about to measure
the sample. Record result displayed (this result is automatically stored in TR7).
USE TABLE
7
Find the "TR" result in the table below to determine the Sodium Chloride concentration in ppm
(parts per million). (Example: a "TR" result of 65.3 (use only the 65 for the chart) equals a Sodium
Chloride value of 4600 ppm). Record result. After testing is completed, rinse cell immediately.

using eXact
Strip Micro CHLORIDE, Part No. 481657. NOTE: To convert the NaCl value to Chloride (Cl
multiply the value from the chart below by 0.6. (Example: 4600ppm NaCl = 2760ppm Cl
