PS-2121
The PS-2121 Colorimeter measures the transmittance (%) of different colors of
light through a solution, and can be used to determine a solution’s concentration.
Colorimeter Quick Start
1. Connect a PASPORT
TM
interface to a USB port on your computer or to a USB hub.
(If using an Xplorer, connect the Xplorer cable to a USB port on your computer.)
2. Connect the sensor to the PASPORT interface (USB Link, PowerLink, Xplorer, etc.).
3. The software launches when it detects a PASPORT
sensor. Select a choice from
the PASPORTAL window.

The recommended sample rate is 1 Hz for color and Beer’s law studies.
If you plan to do reaction order studies, use a faster sample rate.
**
The temperature range applies to both the temperature of the solution in
the cuvette and the ambient temperature. Using the Colorimeter above
or below the recommended range or with condensation may give false
readings.
