1 Introducon
The SP-395 handheld HST uorometer is patented to Pyxis Lab Inc. and not oered anywhere else in the
world. This device ulized UV light absorbance to detect Halogenated TolyTriazole (HST) content in water.
The results are instantaneous and, with proper applicaon understanding, are highly reliable. It is important
to note that this technology is not wet chemistry tesng for azole content and variaons may be observed
depending on the quality of the water sample. In certain waters the background of other organic maer
may cause a false posive reading of azole due to UV absorbance. In consistent makeup water quality with
lile organic loading (ie. city water makeup) and systems with no known organic contaminaon (ie. hydro-
carbon etc..) this technology is very accurate in comparison to wet chemistry methods. The SP-395 does
not dierenate between azole species or reacted versus unreacted azole. The device measures the total
UV absorbance value of the azole and oers the nal value as ppm Halogenated TolyTriazole (HST). It is
incumbent for the user to idenfy the correlaon to exact wet chemistry values and potenal background
interference should be accounted for by checking untreated makeup for UV absorbance signal and remov-
ing that from the nal value measured. The SP-395 will not work in waters containing Nitrite treatment
as Nitrite absorbs UV light and will result in a false high value. With these applicaon limitaons clearly
understood, the SP-395 is commonly used for rapid azole validaon, dramacally reducing service me en-
abling 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 Pyxis SP-395 is an ultraviolet uorometer. It measures Halogenated TolyTriazole (HST) in a water sample
and includes the following features:
• Sample acidicaon is not required. HST measurement is independent of sample pH in the range of
6 to 10.
• Extra color and turbidity parameters measured are used for automac compensaon to eliminate
interference.
• No sample cuvee is needed and variaons associated with the cuvee are eliminated.
• Large color graphic screen that can be read in direct sunlight.

4 Installaon
4.1 Baery Installaon
The SP-395 is powered by four alkaline baeries. Typical baery life lasts for 10,000 measurements or 10
months. When the baery capacity is crically low, the SP-395 will display a ”LOW BATTERY” warning for 5
seconds and then automacally turn o.
*NOTE*Do not use rechargeable nickel cadmium (NiCad) or lithium baeries.
Replace the baeries to resume operaon of the SP-395 aer the baery warning. The SP-395 will auto-
macally turn on in the measurement mode aer new baeries are installaon.
The SP-395 baery compartment, shown in Figure 1, is on the back side of the instrument. Baeries are
held in place by a cover secured with two Phillips-head screws.
Figure 1. The SP-395 baery compartment
Install baeries using the following steps:
1. Remove the baery compartment cover by loosening the two screws.
2. Remove old baeries and dispose of them properly.
3. Following the posive and negave terminal signs in the compartment boom, snap four new AA
alkaline baeries rmly into the baery holder.
4. Replace the baery compartment cover and ensure that the sealing O-ring is lying at on the baery
holder.
5. Fasten the two screws.
*NOTE*Failure to properly seat the O-ring may result in water damage to the SP-395.

5 Instrument Overview
Figure 2.
5.1 Control Keys
The SP-395 has three control keys, as shown in Figure 3. The le ( ), right ( ), and ok ( ) keys
are used to launch acons indicated on the LCD display directly above the keys. The labels above the keys
indicate the funcon associated with each key and funcons can be changed in dierent operaon modes.

5.2 Main Module On/O
To turn on the SP-395: Press momentarily and release.
To turn o the SP-395: Press and hold for about three seconds. Release when the LCD display
turns o. The SP-395 turns itself o aer 60 seconds without user interacon detected. This is done to
conserve baery life.
*NOTE*This auto-me o seng may be customized by the user as desired through the
uPyxis® Mobile or Desktop App.
6 Measurement
6.1 HST Measurement
When powered on, the SP-395 will default to the HST measurement mode. A water sample should be
transferred to the sample cell using a disposable pipee, or the cell can be lled slowly from a sample
bole.
*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-395 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 signicantly dierent than the environmental temperature at which
the SP-395 had been equilibrated (stored).
6.2 High Color and Turbidity Warning
The SP-395 has extra channels to measure sample turbidity and color to automacally 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 HST measurement.

7 Calibraon
HST calibraon for the SP-395 requires deionized (DI) water and a standard soluon. HST calibraon uses
either the 1 ppm or 2 ppm HST standard soluon (see the Oponal Accessories secon).
7.1 HST Calibraon
1. Rinse the sample cell three mes with DI water. Fill the sample cell with DI water.
2. Power on the SP-395 by pressing . Allow 5–10 seconds for the SP-395 to stabilize.
3. Press Calib ( or ) to launch the HST CALIBRATION screen (Figure 4).
4. Press Zero ( ) to start the zero (blank) calibraon.
5. If the calibraon succeeds, a checkmark ( ) and instrucons for the slope calibraon will appear
(Figure 5).
6. Rinse the sample cell three mes with the desired HST standard. Fill the sample cell with the desired
HST standard.
7. Press Cycle ( ) to cycle between the HST standards 1, 2, and 5 ppm (it repeats). Ensure the value
selected matches the desired HST standard in the sample cell.
8. Press Slope ( ) to start the slope calibraon.
9. If the calibraon succeeds, a checkmark ( ), a ”Calibraon Success” message will appear (Figure
6). Otherwise, a warning message is displayed.
10. Calibraon is now complete. Press Exit ( ) to return to measurement mode.
*NOTE*If Exit is pressed before the second checkmark appears, the calibraon will
not be completed and must be re-done.
