• 2-3% by volume in DI water
• May be used in “dry in place” applications
• Epoxy and Polyester powder coat

Fill the bath ¾ full with deionized water and add 25 gallons of FREICON RSX per 1000 gallons of final working solution. Fill to final working volume and mix. While agitating, adjust the pH up to 4.5 using NEUTRALIZER 10L. Heat the solution to operating temperature.

pH:

The pH should be maintained between 4.3 and 4.7 using NEUTRALIZER 10L and FREICON RSX. Adjustment should be made at a rate of 1 quart per 1000 gallons of working solution to avoid overshooting the desired pH range. Do not allow the pH to exceed 5.0 to prevent precipitation of the active ingredients.

• To increase the pH by 0.1 add 1 quart of NEUTRALIZER 10L per 1000 gallons of the bath

• To decrease the pH by 0.1 add 1 quart of FREICON RSX per 1000 gallons of the bath

Concentration:

1. Using a pipet add exactly 2.0 mL of bath sample into a 10 mL graduated cylinder.
2. Using a pipet add exactly 2.0 mL of clean water into a second 10 mL graduated cylinder.
3. Using a pipet add exactly 6.0 mL of Test Solution 60 (1N HCL) to the sample solution
and the water blank cylinders. The cylinder should contain exactly 8ml total volume.
Stopper tightly and shake vigorously at least 12 times.
4. Allow any foam or entrained air to dissipate then add exactly 1.0 mL of Indicating
Solution 27 (0.15% w/v Arsenazo III) to each bath and blank samples. Stopper tightly
and shake vigorously at least 12 times. The resulting solutions should be dark blue to
purple.
5. Pour the blank solution into one of the plastic cells (1-cm path length) provided with the Hach pocket colorimeter.
6. Pour the sample solution into a second plastic cell.
7. Remove the instrument cap from the pocket colorimeter, and insert the cell with the blank
solution into the cell compartment with notch-to-notch fit. Use the instrument cap as a light shield during measurements.
8. Press the ZERO key. The meter should read 0.00. If the meter doesn’t read 0.00, press
the ZERO key again.
9. Replace the blank cell with the bath test solution cell, and cover the cell compartment
with the cap. Press the READ key.
10. Record the reading as absorbance.

The absorbance should be maintained between 0.38 and 0.58. For consistent and accurate results, check battery, clean and dry the outside of the sample cells before inserting them into the pocket colorimeter.
