Getting Started
Equipment Required
A chlorine test requires a 20ml sample cup, a reagent tablet and the
CL200 with a chlorine electrode attached. The optional EX006 Weighted
base is a recommended accessory.
Battery Activation
An insulating tab is located in the battery compartment and prevents
battery drain during storage. It must be removed before use. Refer to the
battery replacement paragraph in the maintenance section.
Measurement Procedure
Sample Preparation:
1. Place the test sample into the sample
cup up to the 20mL line.
2. Drop one reagent tablet into the
sample, wait 10 seconds and then
shake or stir vigorously until it is
dissolved.
Measurement:
1. Press the ON button and insert the electrode into
the sample.
2. Stir the sample with the electrode for 5 to 10
seconds. The “HOLD” indicator will appear after
120 seconds.
Reading:
The value in the display is the total chlorine in ppm.
Note: After running a test, wipe the entire electrode
with a clean/dry paper towel.
