CHLORINE/BROMINE DISK:
NOTE: Samples suspected of having high levels of chlorine,
above 15 ppm, should be pretested with a Wide Range pH/Total
Chlorine Test Strip (2987-G). Samples with high chlorine concentrations will bleach out the chlorine
reagent in the disk and cause false low results.
BIGUANIDE DISK:
Filling
The 3 mL syringe (Code 1189) is used to fi ll the disk with the sample water.
When the syringe is placed in the pool or spa sample, and the plunger is
pulled all the way up, the syringe will hold more than enough sample water to
adequately fi ll the disk. The syringe is held vertically and the tip is inserted into
the fi ll hole on the disk. The plunger is pressed slowly and smoothly to fi ll
the disk.
Three baffl es in the disk ensure that the disk fi lls properly
with less chance of bubbles. The sample water will fi ll the
spaces between the baffl es in a counter-clockwise order.
Each space will fi ll from the bottom to the top. Sample
water should be added until the sample water in the space
after the third baffl e fi lls the top of the space to the
embossed fi ll line.
The disk should not contain any large air bubbles. Air
bubbles will result in erroneous results. The disk should
not be overfi lled. If the disk is over fi lled, sample water
will fl ow out of the overfl ow hole in the center of the disk.
The disk is not leaking.
