2. To verify operation of a FiveStar unit equipped with a chlorine
dioxide sensor, perform response check with the sample line
in place.
3. Since chlorine dioxide is not readily available in cylinders, it is
recommended that either chlorine gas or a chlorine dioxide
generator be used to perform the chlorine dioxide calibration
check. When using chlorine as a check gas, the reading
should be 1/2 (50%) of the known concentration of the
cylinder (e.g., 2 ppm chlorine should read approximately 1
ppm chlorine dioxide).
4. Since shorter sample lines will reduce the reaction with
chlorine gas, calibrate and operate the instrument using the
shortest possible tubing to connect to the calibration
cylinder. Use no more than 10 feet of sample line for best
results. Use only a dedicated regulator with your chlorine
calibration cylinder.
The chlorine dioxide compatible pump has internal parts made of
materials specially chosen to minimize their effects on chlorine
dioxide. Therefore, the following parts must be installed on the
FiveStar unit to properly sample for chlorine dioxide:
PART PART NO.
Sensor Cover
10016244
Sensor Cover Filter
10016245
Pump (if used)
10018395
The chlorine dioxide compatible sensor cover and filter are easy
to recognize; they are completely cut away over the Tox 3
position.

WARNING
Failure to use the appropriate sampling system and
instrument parts when detecting chlorine dioxide may cause
reduced readings. This may lead to serious personal injury
or death.
