1 Introduction

The SP-395T handheld fluorometer is patented to Pyxis Lab Inc. and not offered anywhere else in the world. This device utilized UV light absorbance to detect TolyTriazole (TTA) content in water. The results are instantaneous and with proper application understanding, results are highly reliable. It is important to note that this technology is not wet chemistry testing for azole content and variations may be observed depending on the quality of the water sample. In certain waters the background of other organic matter may cause a false positive reading of azole due to UV absorbance. In consistent makeup water quality with little organic loading (ie. city water makeup) and systems with no known organic contamination (ie. hydrocarbon etc..) this technology is very accurate in comparison to wet chemistry methods. The SP-395T does not differentiate between azole species or reacted versus unreacted azole. The device measures the total UV absorbance value of the azole and offers the final value as ppm TolyTriazole (TTA). It is incumbent for the user to identify the correlation to exact wet chemistry values and potential background interference should be accounted for by checking untreated makeup for UV absorbance signal and removing that from the final 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 application limitations clearly understood, the SP-395T is commonly used for rapid azole validation, dramatically reducing service time enabling water treaters to adjust their programs accordingly. It is important to note however, that there are some applications (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 fluorometer. It measures TolyTriazole (TTA) in a water sample and includes the following features:

• Sample acidification 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 automatic compensation to eliminate interference.
• No sample cuvette is needed and variations associated with the cuvette are eliminated.
• Large color graphic screen that can be read in direct sunlight.

4 Installation

4.1 Battery Installation

The SP-395T is powered by four alkaline batteries. Typical battery life lasts for 10,000 measurements or 10 months. When the battery capacity is critically low, the SP-395T will display a “LOW BATTERY” warning for 5 seconds and then automatically turn off.

NOTE Do not use rechargeable nickel cadmium (NiCad) or lithium batteries.

Replace the batteries to resume operation of the SP-395T after the battery warning. The SP-395T will automatically turn on in the measurement mode after new batteries are installation.

The SP-395T battery compartment, shown in Figure 1, is on the back side of the instrument. Batteries are held in place by a cover secured with two Phillips- head screws.

Figure 1. The SP-395T battery compartment

Install batteries using the following steps:

1. Remove the battery compartment cover by loosening the two screws.
2. Remove old batteries and dispose of them properly.
3. Following the positive and negative terminal signs in the compartment bottom, snap four new AA alkaline batteries firmly into the battery holder.
4. Replace the battery compartment cover and ensure that the sealing O-ring is lying flat on the battery holder.
5. Fasten the two screws.

NOTE Failure to properly seat the O-ring may result in water damage to the SP-395T.

5 Instrument Overview

Figure 2.

5.1 Control Keys

The SP-395T has three control keys, as shown in Figure 2. The left ( ), right ( ), and ok ( ) keys are used to launch actions indicated on the LCD display directly above the keys. The labels above the keys indicate the function associated with each key and functions can be changed in different operation modes.

5.2 Main Module On/Off

To turn on the SP-395T: Press momentarily and release.
To turn off the SP-395T: Press and hold for about three seconds. Release when the LCD display turns off. The SP-395T turns itself off after 60 seconds without user interaction detected. This is done to conserve battery life.

NOTE This auto-time off setting may be customized by the user as desired through the 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 pipette, or the cell can be filled slowly from a sample bottle.

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 times. Allow 5­-10 seconds for the SP-395T to stabilize. The values will be displayed in  if a stable value is reached (Figure 3).

NOTE The time required to reach a stable reading may be slightly longer if the water sample temperature is significantly different than the environmental temperature at which the SP-395T had been equilibrated (stored).

Figure 3.

To convert the reading value to Halogenated Azole (HRA), you may multiply your TTA value reading by a factor of 0.75:

ppm TTA = 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 automatically 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 filter the sample for TTA measurement.

7 Calibration

TTA calibration for the SP-395T requires deionized (DI) water and a standard solution. TTA calibration uses either the 1 ppm or 2 ppm TTA standard solution (see the Optional Accessories section).

11 Device Maintenance and Precaution

11.1 Maintenance Best Practices and Quick Tips

For greatly increased working life and ease of use of the SP-395T follow the list of maintenance best practices and quick tips below:

• Rinse the sample cell at least three times with the desired solution before turning on.
• After a successful calibration, the unit does not automatically return to the measurement mode. If Exit is held down too long the unit will power down rather than returning to the measurement mode.
• After returning to measurement mode after calibration, rinse several times with the first sample. The unit will continue to read the sample values without any further key presses if it has not powered off. If there are no key presses for 20 seconds the screen will darken, and after another 20 seconds without key activity will power down. The press of any key while the screen is dark will reset the timer and the screen will re-light. (This press will not step along the calibration process; the next press needed will still be required in the sequence).
• Always rinse the unit with clean water after use and dry by clean tissue or paper towel.

11.2 Methods to Cleaning the SP-395T

A light deposit on quartz glass inside the conductivity cell can be cleaned by a Q-tip. Aged heavy deposition, especially iron oxide deposited, can be removed using a cleaning solution that is capable of removing iron, such as the Pyxis Handheld Device Cleaning Solution Kit (P/N: SER-02) available from Pyxis online E-Store https://pyxis-lab.com/product/handheld-device-cleaning- kit/.

Figure 23. Handheld Device Cleaning Solution Kit

To clean the SP-395T pour cleaning solution into the sample cell for 10 minutes. Rinse the sample cell with distilled water and use the Cleanliness Check (see the Sample Cell Cleanliness Check section) to confirm that the SP-395T is clean. Repeat the process as needed until the Cleanliness Check shows .

11.3 Storage

Do not expose the SP-395T to an extreme high or low temperature condition such as leaving the SP-395T inside an unattended automobile.
