Product Summary
The PASPORT Water Quality Colorimeter is designed specifically to support the chemical analysis of water samples using PASCO’s ezSample Snap Vial test kits (sold separately). It includes built-in calibration curves for determining the concentration of ions in the solution, making it incredibly simple to use in the classroom or field.
How It Works
The colorimeter accurately measures the absorbance by projecting 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.
What's Included
- 1x PASPORT Sensor Extension Cable
