NeuLog® Oxygen Sensor

(in stock)


Smart, easy, and affordable digital data collection technology for now and the future

The next generation of scientific data collection sensors is now available—easier to use, more versatile, and with a lower cost than any other data collection system. For both beginners and advanced users, NeuLog® data logger sensors offer a simple and flexible solution to collect and analyze the most complex data from your science laboratory experiments or field activities.

This sensor is 2 oxygen sensors in 1 low-cost unit! Primarily used for experiments in biology and environmental science, the NeuLog® Oxygen Sensor measures the level of free oxygen in air or dissolved oxygen in water. The free-oxygen-in-air mode measures changes in oxygen levels during combustion or in reactions that produce oxygen (e.g., hydrogen peroxide decomposition). The dissolved-oxygen mode is useful in the study of photosynthesis and the levels of dissolved oxygen in natural environments. The oxygen sensor is designed for quick sampling in the school laboratory and in the field. It employs easy-to-use polarographic (Clark) technology; replaceable membranes are available. With its integral thermistor, housed in stainless steel and sealed on the electrode's outer wall, the sensor provides dependable, temperature-compensated measurements. The electrode itself is constructed of super-tough Delrin® for long-term durability. Calibrate the sensor easily: Just connect the sensor to power (the USB module plugged into a computer or the NeuLog® Digital Display Unit [item #369730] and the NeuLog® Battery Pack Module [item #369732]). Calibrate the probe simply in open air, taking this as a standard level of 20.9% (assuming stable level in the Earth's atmosphere at sea level) and pressing the push button on the sensor's box for about 3 seconds when the readings are stable. The sensor will then be calibrated at 20.9%.

Note: Requires connection hardware, which is sold separately. For hardwired setup, use the NeuLog® PC Starter Connection Bundle (item #369500) or NeuLog® USB Bridge Module (item #369733). For wireless setup, use the NeuLog® Wi-Fi™ Starter Connection Bundle (item #369510). For stand-alone setup, use the NeuLog® Graphic Display Bundle (item #369520).
