if the pumping rate exceeds a desired maximum limit.
The ST-730 series probe is designed to be easily removed, inspected, and cleaned if required. It is suggested
that the ST-730 series probe be checked for fouling and cleaned on a monthly basis. Heavily contaminated
waters may require more frequent cleanings. Cleaner water sources with less contamination may not re-
quire cleaning for several months.

Methods to Cleaning ST-730 Series Probe
Any equipment in contact with industrial cooling systems is subject to many potential foulants and con-
taminants. Our inline probe cleaning solutions below have been shown to remove most common foulants
and contaminants. A small, soft bristle brush, Q-Tips cotton swab, or soft cloth may be used to safely clean
the probe housing and the quartz optical sensor channel. These components and more come with a Pyxis
Lab
Inline Probe Cleaning Solution Kit
(P/N: SER-01) which can be purchased at our online Estore/Catalog

Figure 20. Inline Probe Cleaning Solution Kit
To clean the ST-730 series probe, soak the lower half of the probe in 100 mL inline probe cleaning solution
for 30 minutes. Rinse the ST-730 series probe with distilled water and then check for the flashing blue light
inside the ST-730 series probe quartz tube. If the surface is not entirely clean, continue to soak the ST-730
series probe for an additional 30 minutes. Use the small, soft bristle brush and Q-Tips cotton swabs as
necessary to remove any remaining contaminants in the ST-730 series probe quartz tube.

Storage
Avoid long term storage at temperature over 100 °F. In an outdoor installation, properly shield the ST- 730
series probe from direct sunlight and precipitation.
