Pyxis ST-601
Operation Manual

The primary method is to install the ST-601 probe in-line with of the suction side of the chemical
feed pump in piping format. This method should ideally in a vertical line run to avoid chlorine
dioxide gas bubble interference. This can be done with the standard ST-001 Inline Tee Assembly
(3/4” FNPT) provided with each sensor. Pyxis also offers 2”
,
3”
and 4
”
inline tee assemblies as an
accessory option if required.
TEFLON TUBING INSTALLATION FORMAT
The second method is to install the probe in-line using t
he unique ¼” OD (7mm OD) clear Teflon
tubing adapter 6 inches in length. This tubing can be passed “THROUGH” the optical channel to
allow for use of the sensor with smaller chemical feed line installations on the suction side of the
chemical feed pump. U
sers can use conventional ¼” OD Compression Fittings to connect desired
inlet and outlet chemical line size to the ST-601 sensor in this format. As this the inline Pipe
installation method, Pyxis recommends installation on a vertical run, ideally on the suction side.
*NOTE* for enhanced ambient light interference prevention, Pyxis recommends users apply black
electrical tape or shrink wrap to allow sample darkening prior to and after the optical channel as
seen in the sensor photo in the Section 2 of this manual.
