The redesigned small form optical dissolved oxygen sensor is compatible with all standard 12 mm probe classroom stands and stoppers.
See the Buying Guide for this item's required, recommended, and additional accessories.
Product Summary
The Wireless Optical Dissolved Oxygen (ODO) Sensor is ideal for monitoring DO2 in the lab or field. The new design takes the circuitry of our previous version (PS-3224) and compacts it into a much smaller form factor for easier use with bench scale equipment. The new design follows the standard probe tip (12 mm) shape and size shared by most solution-based probes and the equipment that houses them; this upgrade allows for elegant use in classroom settings regardless if you utilize beakers, flasks, or PASCO's Photosynthesis Tank or Chamber. Plus, the 3 meter cable allows students to easily measure oxygen levels in class aquariums, reaction vessels, as well as from the shores of creek or wetland sites.
The Wireless ODO Sensor automatically compensates for temperature and pressure when reporting values, and the optical technology is accurate, fast, and does not require stirring, filling solutions, warm-up, or frequent calibration.
Remotely log data using the sensor's built-in memory, or stream your data to your device in real time. After collecting data for hours (or even days!), simply connect the sensor to your device to download your data. With this powerful sensor, educators can explore day and night nutrient cycles, changes in metabolic processes, seasonal changes in water quality, and more.
