Vernier Optical DO Probe

Description

The Vernier Optical DO Probe uses luminescent technology to provide fast, easy, and accurate results, making it a terrific choice for biology, ecology, or environmental science courses. Students can measure dissolved oxygen concentration in surface water or to perform a wide variety of experiments to determine changes in dissolved oxygen levels, one of the primary indicators of the quality of an aquatic environment.

• Plug-and-play technology–no filling solution, warm-up time, stirring, or calibration necessary
• Built-in temperature and pressure compensation
• Easy maintenance
• Switch setting to measure in units of mg/L or % saturation

The Optical DO Probe cap is warranted to be free from defects for a period of one year from the date of purchase. With proper use, the lifetime of the cap may be longer than one year.
