Introduction
The PASPORT Water Quality Colorimeter is designed for chemi-
cal analysis of water samples using PASCO's ezSample Snap Vial
water quality test kits.
ezSample Snap Vials contain a reagent (specific to a particular
ion) in a vacuum-sealed ampoule. When the scored tip of the
ampoule is snapped off in the water sample, the sample is drawn
into the ampoule and mixes with the color-forming reagent. The
absorbance of the resulting solution depends on the ion concen-
tration.
The colorimeter accurately measures the absorbance by project-
ing light through the ampoule and measuring the intensity of
transmitted light. It uses Beer's Law and built-in calibration
curves to calculate the ion concentration.
The colorimeter's measurements are sent to your PASPORT
interface for display, recording, and analysis.
