a. Vernier optical do Probe, OrDer cODe odo-bta, $379<br />
Students can now measure the concentration of dissolved<br />
oxygen in water quickly and easily with the new Vernier Optical<br />
DO Probe. The Vernier Optical DO Probe uses luminescent<br />
technology to provide fast, easy, and accurate measurements<br />
of dissolved oxygen concentrations, making it a terrific choice<br />
for biology, ecology, or environmental science courses. This<br />
probe can be used to measure dissolved oxygen concentration<br />
in surface water or to perform a wide variety of experiments<br />
to determine changes in dissolved oxygen levels, one of the<br />
primary indicators of the quality of an aquatic environment.<br />
• plug-and-play technology —no filling solution, warm-up time,<br />
calibration, or stirring necessary<br />
• built-in temperature and pressure compensation<br />
• easy maintenance<br />
• Switch setting allows units of mg/l or % saturation<br />

OrDer cODe odo-grd, $45<br />
attach the metal guard to the Vernier Optical DO probe to<br />
protect the cap and to help weigh down the probe when<br />
submerged.<br />
