Pyxis SP-395T TolyTriazole (TTA) Handheld
Patented handheld device measuring UV absorbance of TolyTriazole (TTA) at 0-10ppm, no reagents or cuvettes required.
Pyxis SP-395T TolyTriazole (TTA) Handheld
The Pyxis SP-395T is a patented handheld fluorometer that uses UV light absorbance to detect TolyTriazole (TTA) content in water, delivering instantaneous, reliable results without acidifying the sample. Because the technology is not wet chemistry, users should establish correlation to wet chemistry values and account for background interference. The device is not suited to waters containing nitrite treatment, which causes a false high reading.
Description
The Pyxis SP-395T is a patented handheld fluorometer that uses UV light absorbance to detect TolyTriazole (TTA) content in water, a common corrosion inhibitor in cooling and process water treatment. It delivers instantaneous, reliable results without requiring sample acidification, simplifying field testing compared to traditional wet chemistry methods.
Because the underlying technology is not wet chemistry, value variations can occur depending on sample water quality; users should establish the correlation to exact wet chemistry values and account for background interference. The device automatically compensates for colour and turbidity, and does not work correctly in waters containing nitrite treatment, as nitrite absorbs UV light and causes a false high value.
With no sample cuvette required and a large colour graphic screen visible in direct sunlight, the SP-395T gives cooling water treatment programs a quick way to verify TTA residuals across a 0.1-10.0ppm range with ±0.1ppm accuracy.
Why Use This
Faster Corrosion Inhibitor Checks
Instant UV absorbance detection of TolyTriazole means field technicians get results without acidifying samples or waiting on wet chemistry.
Built for Field Conditions
Automatic colour and turbidity compensation, along with a sunlight-readable screen, keep the SP-395T practical for outdoor and plant-floor use.
Applications
- Cooling water treatment — verifying TolyTriazole corrosion inhibitor residuals
- Industrial process water — field checks of TTA levels without acidification steps
FAQ
What does the SP-395T measure?
It measures TolyTriazole (TTA) content in water using UV light absorbance, over a range of 0.1-10.0ppm with ±0.1ppm accuracy.
Do I need to acidify the sample first?
No, sample acidification is not required, which simplifies testing compared to wet chemistry methods.
How does the meter handle coloured or turbid samples?
It automatically compensates for colour and turbidity interference.
Are there water conditions where results may be inaccurate?
Yes. The SP-395T is not suited to waters containing nitrite treatment, since nitrite absorbs UV light and causes a false high reading; users should also correlate readings to wet chemistry values given the technology is not wet chemistry.
