Sensors<br />
Conducting an acid-base titration<br />
using Go Direct pH, Go Direct<br />
Drop Counter, and Stir Station<br />
Go Direct Colorimeter<br />
GDX-COL<br />
Use this sensor to explore absorbance and percent<br />
transmittance in a variety of experiments including<br />
Beer’s law (absorbance vs. concentration) and kinetic<br />
studies (concentration vs. time). Students select<br />
between four wavelengths (430 nm, 470 nm,<br />
565 nm, and 635 nm) to set up their experiment.<br />

Go Direct Conductivity<br />
GDX-CON<br />
Investigate the difference between ionic and molecular<br />
compounds or measure Total Dissolved Solids (TDS). Our<br />
Go Direct Conductivity determines the ionic content of an<br />
aqueous solution by measuring its electrical conductivity (up<br />
to 20,000 μS/cm). The sensor includes automatic temperature<br />
compensation for general use that can be turned off to<br />
perform conductivity studies as a function of temperature.<br />
