Pyxis ST-540A

0-500 ppb


NDSA Inline Fluorometers

For Research Use in Industrial Water Treatment
Description
Many companies in the water treatment industry have expressed a desire to evaluate this unique
fluorescent tracer for high pressure boiler water tracing applications. The ST-540 Series are inline
fluorometers designed for those desiring to conduct research and development of NDSA traced boiler
or process water treatment programs. The ST-540 Series offer direct measurement of NDSA (Napthenic
Disulfonic Acid CAS# 1655-29-4) utilizing LED light sources for use in boiler water and boiler feedwater
measurement applications.

The ST-540 Series offers Pyxis proprietary algorithms to determine the concentrations of NDSA in a
range of 0-500ppb while simultaneously measuring light loss through the optical channel to determine
sensor cleanliness. The ST-540 Series offer a combination of 4-20mA as well as RS-485 Modbus output
signals and is Bluetooth Enabled for wireless cleanliness diagnostics and calibration when used with MAWB
or PowerPACK Series Bluetooth Adapters and the uPyxis APP for Mobile or Desktop devices. The
ST-540 Series is provided in both UPVC and 304 stainless steel for use in a cooling/process water or
cooled/pressurized sample (<120oF) of boiler water or boiler feedwater. Each sensor is provided with a
1.5m bulk-head cable with 7-Pin quick adapter and 1.5m flying lead cable with 7-Pin quick adapter,
enabling rapid wiring to any microprocessor controller, PLC or DCS system. The MA-WB Bluetooth
adapter may be inserted between ST-540 sensor cable and flying lead cable to enable wireless access for use with the uPyxis Mobile or Desktop APPs for diagnosis and calibration.
