Pyxis is 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.
Specially designed for water treatment companies, PTSA measurement displays
product concentration in ppm along with the product name, or PTSA in ppb. The
user can choose a product name from a user-defined dropdown list of 5 product
names.
Automatically select the primary wavelength according to the method selected and
switches to the secondary wavelength to extend the primary measurement range.

Display a concentration-time profile curve during the last time period in a
colorimetric measurement. The user can terminate the timing process and take a
reading if the displayed concentration reaches a plateau before completing the
predefined time period.
The user can update the calibration parameter of any pre-calibrated colorimetric
method by testing a standard solution first and then following a setup procedure to
update the calibration parameters.
