1 Introduction
The Pyxis SP-380 is a uniquely designed handheld multimeter that measures both PTSA and Fluorescein,
simultaneously. It is a cuvette-less device. Less than 5 mL water sample is needed to fill the sample cell for
proper measurement.
1.1 Main Features
The SP-380 includes the following features:
• Simultaneous measurement of the concentration of fluorescent tracer PTSA and the concentration
of fluorescent tracer Fluorescein of a water sample.
• Pre-calibrated for measuring PTSA (pyrenetetrasulfonic acid) in the range of 0 to 300 ppb.
• The fluorescence PTSA measurement is automatically compensated for sample color and turbidity
interference.
• Large color graphic screen that can be read in direct sunlight.
