1 Introducon
The ST-565 Series inline uorometers are patented to Pyxis Lab Inc. These devices ulized UV light uores-
cence to detect Halogenated Tolytriazole (HST with ST-565) and Tolytriazole (TTA with ST-565T) content in
water. The results are instantaneous and, with proper applicaon understanding, results are highly reliable.
It is important to note that this technology is not wet chemistry tesng for azole content and variaons may
be observed depending on the quality of the water sample. In certain waters the background of other or-
ganic maer may cause a false posive reading of azole due to UV uorescence or absorbance. Inconsistent
makeup water quality with lile organic loading (ie. city water makeup) and systems with no known organic
contaminaon (ie. hydrocarbon) this technology is very accurate in comparison to wet chemistry methods.
The ST-565 Series probe does not dierenate between azole species or reacted versus unreacted azole.
The device measures the total UV uorescence signature of the azole and oers the nal value as ppm
Halogenated Tolytriazole (HST with ST-565) and Tolytriazole (TTA with ST-565T). It is incumbent for the user
to idenfy the correlaon to exact wet chemistry values and potenal background interference should be
accounted for by idenfying untreated makeup for UV uorescent signal and removing that from the nal
value measured.
The ST-565 Series probe will not work in waters containing Nitrite treatment as Nitrite absorbs UV light
and will result in a false high value. With these applicaon limitaons clearly understood, the ST-565 Se-
ries probe is commonly used for rapid azole validaon, dramacally reducing service me enabling water
treaters to adjust their programs accordingly. It is important to note however, that there are some applica-
ons (surface makeup water systems or high organic loading/contaminated systems) where this technology
is not ideal due to a high degree of interference. The user needs to understand the dynamics of their system
and evaluate its use accordingly.
1.1 Main Features
The ST-565 Series measures Halogenated Tolytriazole (HST with ST-565)/Tolytriazole (TTA with ST-565T) in
a water sample and includes the following features:
• Easy calibraon with using uPyxis® Mobile or Desktop App.
• Automac compensaon for turbidity and color.
• Water sample does not need to be acidied. Sample pH between 6.4 to 10.0 and the sample PTSA
concentraon (<300 ppb) do not aect the azole measurement.
• Diagnosc informaon (probe fouling, color or turbidity over range, failure modes) are available in
uPyxis® App or via Modbus RTU.
• Easy to remove from the system for cleaning and calibraon without the need for any tools.

3 Unpacking Instrument
Remove the instrument and accessories from the shipping container and inspect each item for any damage
that may have occurred during shipping. Verify that all accessory items are included. If any item is missing
3.1 Standard Accessories
• Tee Assembly 3/4” NPT (1x Tee, O-ring, and Nut) P/N: ST-001
• 7-Pin Female Adapter/Flying Leads Cable (2 ) P/N: MA-1100
• User Manual available online at hps://pyxis-lab.com/support/
4 Installaon
4.1 Piping
The ST-565 Series probe can be installed in an inline ow applicaon using the included Pyxis ST-001 Inline
Tee Assembly. The ST-001 oers 3/4” FNPT thread or socket weld adapters with unions for easy installaon
and sensor maintenance. To properly install the ST-565 Series probe into the ST-001 Tee Assembly, follow
the steps below:
1. Insert the provided O-ring into the O-ring groove on the tee.
2. Insert the ST-565 Series probe into the tee.
3. Tighten the tee nut onto the tee to form a water-ght, compression seal.

4.2 Wiring
If the power ground terminal and the negave 4–20mA terminal in the controller are internally connected
(non-isolated 4–20mA input), it is unnecessary to connect the 4–20mA negave wire (green) to the 4–20mA
negave terminal in the controller. If a separate DC power supply other than that from the controller is used,
make sure that the output from the power supply is rated for 22–26 VDC @ 65 mA.
*NOTE*The negave 24V power terminal (power ground) and the negave 4–20mA ter-
minal on the ST-565 Series probe are internally connected.
Follow the wiring table below to connect the ST-565 Series probe to a controller:

4.3 Connecng via Bluetooth
A Bluetooth adapter (P/N: MA-WB) can be used to connect a ST-565 Series probe to a smart phone with the
uPyxis® Mobile App or a computer with the uPyxis® Desktop App.
Figure 3. Bluetooth connecon to ST-565 Series probe
4.4 Connecng via USB
A USB-RS485 adapter (P/N: MA-485) can be used to connect a ST-565 Series probe to a computer with the
uPyxis® Desktop App.
*NOTE*Using non-Pyxis USB-RS485 adapters may result in permanent damage of the ST-
565 Series probe communicaon hardware.

5 Setup and Calibraon with uPyxis® Mobile App
5.1 Download uPyxis® Mobile App
Download uPyxis® Mobile App from Apple App Store or Google Play.
Figure 5.
5.2 Connecng to uPyxis® Mobile App
Turn on Bluetooth on your mobile phone (Do not pair the phone Bluetooth to the ST-565 Series probe).
Open uPyxis® Mobile App. Once the app is open the app will start to search for the sensor. Once the
uPyxis® Mobile App connects to the sensor, press the ST-565 Series probe.
