CL17 Free and Total Chlorine Calibration/Verification
Supplied Apparatus and Reagents
The Voluette contains a chlorine standard in the range 100–130 mg/L. Each Voluette is
precisely analyzed by Hach Company prior to shipment and the actual chlorine
concentration is printed on the tube container. When mixed with on of the bottles of
organic Free Water, a Chlorine Standard in the range 4.5 to 5 mg/L is produced. The
precise value of the standard is calculated as shown in
Preparing the Chlorine Standard

Installing the 3-Way Valve
1. Turn off the analyzer power.
2. Turn off flow to the analyzer.
3. Determine if your analyzer is “Old Style”, or “New Style”. Refer to Figure 1 on page 1 .
4. If it is a new style analyzer, disconnect the sample in line by pushing the ring on the
John-Guest fitting in and pulling the tubing out, see
Figure 2 on page 4 . If it is an old
style analyzer, it will be connected with a plastic nut; disconnect the nut and remove
the ferrule by cutting the tubing just above it. Allow the excess water to drain into a
container or paper towel.
5. If this is an old style analyzer, skip this step. If it is a new style analyzer, cut about
½-
inch off of the end of the tube just removed. Discard the ½- inch piece.
6. Cut a 2- inch piece off of the end of the tubing and insert the barbed end of the female
luer fitting into this piece. Make sure the barbed end is pushed in until the tubing is
snug against the luer end. Install the barbed end of the male luer into the end of the
tubing that is attached to the sample line. See
Figure 2 on page 4 .
7. Attach the 3-Way luer lock valve to the male and female luer fittings. Hand-tighten,
making sure the fittings are snug, but do not over-tighten. Do not use tools on
luer-type fittings. Do not attach anything to the center port on the valve at this time.
See
Figure 3 on page 5 .
8. Push the end of the 2-inch long piece of tubing back into the John-Guest fitting,
making sure that the tube goes through both o-rings in the fitting. If it is an old style
analyzer, reinstall the tubing in the fitting and screw the fitting back onto the analyzer.
