1 Introducon
The SP-395T handheld uorometer is patented to Pyxis Lab Inc. and not oered anywhere else in the
world. This device ulized UV light absorbance to detect TolyTriazole (TTA) 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 organic maer may
cause a false posive reading of azole due to UV absorbance. In consistent makeup water quality with lile
organic loading (ie. city water makeup) and systems with no known organic contaminaon (ie. hydrocarbon
etc..) this technology is very accurate in comparison to wet chemistry methods. The SP-395T does not
dierenate between azole species or reacted versus unreacted azole. The device measures the total UV
absorbance value of the azole and oers the nal value as ppm TolyTriazole (TTA). It is incumbent for the
user to idenfy the correlaon to exact wet chemistry values and potenal background interference should
be accounted for by checking untreated makeup for UV absorbance signal and removing that from the nal
value measured. The SP-395T 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 SP-395T
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 applicaons
(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 Pyxis SP-395T is an ultraviolet uorometer. It measures TolyTriazole (TTA) in a water sample and includes
the following features:
• Sample acidicaon is not required. TTA measurement is independent of sample pH in the range of
6 to 10.
• Extra color and turbidity parameters measured are used for automac compensaon to eliminate
interference.
• No sample cuvee is needed and variaons associated with the cuvee are eliminated.
• Large color graphic screen that can be read in direct sunlight.

4 Installaon
4.1 Baery Installaon
The SP-395T is powered by four alkaline baeries. Typical baery life lasts for 10,000 measurements or 10
months. When the baery capacity is crically low, the SP-395T will display a ”LOW BATTERY” warning for
5 seconds and then automacally turn o.
*NOTE*Do not use rechargeable nickel cadmium (NiCad) or lithium baeries.
Replace the baeries to resume operaon of the SP-395T aer the baery warning. The SP-395T will auto-
macally turn on in the measurement mode aer new baeries are installaon.
The SP-395T baery compartment, shown in Figure 1, is on the back side of the instrument. Baeries are
held in place by a cover secured with two Phillips-head screws.
Figure 1. The SP-395T baery compartment
Install baeries using the following steps:
1. Remove the baery compartment cover by loosening the two screws.
2. Remove old baeries and dispose of them properly.
3. Following the posive and negave terminal signs in the compartment boom, snap four new AA
alkaline baeries rmly into the baery holder.
4. Replace the baery compartment cover and ensure that the sealing O-ring is lying at on the baery
holder.
5. Fasten the two screws.
*NOTE*Failure to properly seat the O-ring may result in water damage to the SP-395T.

uPyxis® Mobile or Desktop App.
6 Measurement
6.1 TTA Measurement
When powered on, the SP-395T will default to the TTA measurement mode. A water sample should be
transferred to the sample cell using a disposable pipee, or the cell can be lled slowly from a sample
bole.
*NOTE*Special care should be taken when pouring the sample into the cell to avoid air
bubble entrainment, which can interfere with reading accuracy. It is recommended to use
the 3 mL Transfer Pipet to best avoid air bubbles.
Before beginning a measurement, use the sample water to rinse the sample cell at least three mes. Allow
5–10 seconds for the SP-395T to stabilize. The values will be displayed in white with a blue background if
a stable value is reached (Figure 3).
*NOTE*The me required to reach a stable reading may be slightly longer if the water
sample temperature is signicantly dierent than the environmental temperature at which
the SP-395T had been equilibrated (stored).
To convert the reading value to Halogenated Azole (HRA), you may mulply your TTA value reading by a
factor of 0.75:
ppm T T A = 0.75 ×ppm HRA (1)
6.2 High Color and Turbidity Warning
The SP-395T has extra channels to measure sample turbidity and color to automacally compensate sample
color and turbidity interference. If sample turbidity and color values determined are too high, a warning
will be displayed. In such a case, the user should lter the sample for TTA measurement.

7 Calibraon
