Vernier Optical DO Probe
The Vernier Optical DO Probe makes it easy to measure the dissolved oxygen concentration in water. Perfect for the field or for the laboratory, this plug-and-play probe requires no calibration, no filling solution, no warm-up time, and no stirring.
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 two years from the date of purchase. With proper use, the lifetime of the cap may be longer than two years.
